But if you like eating a normal breakfast, then it’s still fairly simple: bacons, eggs, avocado, and then one or two keto coffees. If you have 3 eggs, that’s 15g of fat. Your goal is to get at least one third of your fat for the day first thing in the morning so you don’t have to worry about it as much later. To figure out that number, you can calculate your TDEE and then figure out what 70% of that is in grams of fat… Since most of the breakfast foods we’ve looked at are in the 15g of fat range, we can make the rule simpler: divide your goal weight by 30, round up, and thats how many “fat servings” you should have for breakfast. This seems like a lot of thinking right now, but once you figure out what your number is and find a breakfast mix that you like you never have to think about it again.|Keto dieters drastically cut carbohydrates to about 10 percent of their daily diet, which in some cases can be just 20 grams of carbohydrates per day. That amount of carbohydrates is equivalent to one slice of white bread per day, according to Feller. Nutritionists also stress that followers of a keto diet should get their fat intake from healthy fats like olive oils and nuts. Samantha Kafedzic, 31, has lost 17 pounds since starting on a keto diet four weeks ago. Kafedzic, who admits she now eats “very different” meals from her daughter, said she feels better overall in addition to the weight loss. “I have more energy with this one running around,” Kafedzic said, pointing to her daughter. “My workouts are so much better. The key to being successful on the keto diet is getting about 20 percent of your calories from protein and eating lots of fat. For some keto followers, the amount of fat could equal more than 70 percent of their diet. The amount of fat someone following the keto diet may consume in one day could be more than five times the recommended intake for daily fat for the average American, according to Feller. The diet’s critics argue that it is nearly impossible to follow long-term, could lead to muscle loss and could deprive your brain of its preferred source of fuel, carbohydrates. Feller agrees that the keto diet is not a diet she would recommend following for an extended period of time. “The jury is out on if that is safe for the long term,” she said. “What most studies say is that you can follow a ketogenic diet for some months. She also says that the body flushes out the buildup of ketones in urine, which also depletes water and sodium from the body. All that to say: Drink up. Tucci recommends waking up to a large glass of water and sipping regularly throughout the day to reach a goal of consuming half of your body weight in ounces of water daily. As your body transitions from a carbohydrate burner to a fat burner, you may experience what’s known as the “keto flu,” or flu-like symptoms (including muscle cramps, nausea, aches, and fatigue) during the first two weeks of the keto diet. If you’re not prepared for this feeling, you may think something is drastically wrong and give up the diet completely. More than that, you can help yourself through the transition period of low energy by planning out your meals or meal prepping, says Clevenger. She also recommends eating foods rich in potassium, magnesium, and sodium, as well as hydrating to help ease keto flu symptoms. Increases energy, allowing those who typically don’t like to exercise to be excited about it. An insulin response is associated with fatigue, and when we keep our carbohydrate load down below 30-40 g/day, we just don’t have that much of an insulin response. Gives you a quick-win with a 5-15 pound weight loss the first week. Yes, this is water weight, but seeing the number drop so drastically, with bloating go down, provides a boost of self confidence. Reduces anxiety, depression, and gives a general sense of well being within the first week (source), which can help those tremendously who typically stress eat. Tames hunger because the body’s process of running on fat, not carbs, acts as a natural appetite suppressant. Reduces insulin response and blood sugar crashes. It’s common for those who previously self-described themselves as the type of people who ‘never skipped a meal’ to now realize they completely forgot to eat lunch, or they can skip breakfast and still go work out - no problem. Your body will constantly be searching for the nutrients it needs if you don’t give it enough protein and that’s why many women say they eat great all day, but after dinner they can’t stop snacking. If you want to lose body fat, use the fat macros that you’ve calculated from the keto calculator as your LIMIT not as a goal to reach. This is very important to understand. You want to use your own body fat stores for energy, therefore eating too much dietary fat will only help you use that fat for energy and not your own stored fat. If you have fat to lose, then eating say, 50- 60% dietary fat on a daily basis will allow your own body to use your own fat stores for energy as opposed to just burning the dietary fat you ingest. Here is a list of the best options for cooking and frying. You want oils that are low in PUFA (Poly Unsaturated Fatty Acids) and high in SFA (saturated fatty acids) because SFA are more stable and are less likely to get oxidized and cause inflammation.
Well, while they have roughly the same nutritional value as any other type of beans, green beans and black soybeans are particularly low in carbs: “A 1/2 cup of black soybeans provides only eight grams of carbs, 11 grams of protein, seven grams of fiber, and six grams total of fat,” Gans notes. If you’re looking for a little bit more info on bean types and their various carb counts according to the USDA database, see below. Each of these nutritional values are determined based on half cup measurements. What are some good bean substitutes? Now that you have all the information you need on beans and their relationship to the keto diet, you might be wondering how you can work other low-carb, similarly-textured foods into your everyday eats and meal prep. (Or, if you just don’t like beans in general, you might be looking for some substitutes.) Here are some great go-to options, according to Sheth. Mushrooms. Because of their textured and earth-y taste, chopped mushrooms are a great substitute for any bean-centered meals if you’re looking for a swappable option. Eggplant. “Consider other low-carb vegetables as a swap for beans,” says Sheth. She recommends changing out carb-heavy options like hummus for eggplant-based dips like babaganoush. Peanuts. Yep, boiled peanuts are legumes, and they can totally be a go-to if you’re looking for a bean substitute. Why? “They are low in carbs and can provide a similar texture to dishes,” says Sheth. Avocado. Looking for a high-fat, low-carb substitute for your favorite beans? Avocados or dips like guacamole are a flavorful and easy-to-incorporate option, Sheth says. Ground meat. High-protein, lean ground meats are also a flavorful and filling substitute for beans, if you’re not on a vegetarian or vegan diet.|The ketogenic diet (also referred to as the keto diet) has been around for decades, but recently it’s grabbing headlines for its ability to enhance performance and melt pounds. But are these claims legit? And, more important, is it safe? “I get asked all of the time ‘What is the keto diet” followed by ‘Do you think I should do it,’” says Kelly Nohl, a registered dietitian with Henry Ford Health System. Here, Nohl answers those questions - and many more - so there’s no need to wonder about this popular diet plan anymore. Q: What is the ketogenic diet? A: The ketogenic diet (also called keto) dates back to the 1920s, when doctors began using it to control seizures among patients with epilepsy. The diet’s composition of carbohydrates, fat and protein force the body to use fat instead of carbohydrates for energy. Dubbed ketosis, this process creates acids in the blood called ketones that our bodies and brains use for fuel. It's advertised as a weight-loss wonder, but this eating plan is actually a medical diet that comes with serious risks. In the world of weight-loss diets, low-carbohydrate, high-protein eating plans often grab attention. The Paleo, South Beach, and Atkins diets all fit into that category. They are sometimes referred to as ketogenic or "keto" diets. But a true ketogenic diet is different. Unlike other low-carb diets, which focus on protein, a keto plan centers on fat, which supplies as much as 90% of daily calories. And it's not the type of diet to try as an experiment. Kathy McManus, director of the Department of Nutrition at Harvard-affiliated Brigham and Women's Hospital. How does the keto diet work? Here are the basics of keto: The diet aims to force your body into using a different type of fuel. Instead of relying on sugar (glucose) that comes from carbohydrates (such as grains, legumes, vegetables, and fruits), the keto diet relies on ketone bodies, a type of fuel that the liver produces from stored fat. And they are-just leveling with you here-pretty difficult diets to maintain long-term, both in terms of general enjoyment and food-related sanity. If you're interested in either of these diets (and you are aware that you don't need to go on a diet to have a healthy diet), it's important to know the basics of each, and how they compare to one another. To help you sort out the nuances between Keto and Paleo, we talked with registered dietitian Kristen Kizer, of Houston Methodist Hospital in Texas. What is the Paleo Diet? THE PALEO DIET focuses on foods that are high in protein and rich with fiber. There's a strong emphasis on meat, fruits, and vegetables-basically, anything our ancestors would have consumed more than 10,000 years ago during the Paleolithic era. Because hunter-gatherers like Otzi had limited technology, obviously things like frozen pizza aren't allowed on the diet. But many foods that are considered healthy, like whole grains and legumes, are also not allowed.|Acne - can keto or low-carb diets cure it?

One concern voiced in some studies is loss of muscle tissue beyond what might be expected from any calorie-restricted weight loss diet, possibly because the body is attempting to break down protein to create glucose, but Volek says this isn't an issue when the ketogenic diet is followed correctly. Could the ketogenic diet's extreme restriction of carbohydrates contribute to micronutrient deficiencies and impact gut health? Ketogenic diets don't just eliminate sugar and refined carbohydrates; they also curtail pulses, whole grains, fruit, and starchy vegetables. All of these foods contribute vitamins, minerals, antioxidants, phytochemicals, and fiber-including prebiotic fiber that promotes a healthy gut microbiota. Numerous studies have demonstrated that the ketogenic diet alters the gut microbiota in ways that have benefit for reduction of epileptic seizures,15 but research is lacking on the impact in populations using the diet for weight loss or diabetes management. Somerville, Massachusetts-based Jessi Haggerty, RDN. She also points out that when people on a ketogenic diet are consuming large quantities of nonstarchy vegetables, the excessive amounts of insoluble fiber also can lead to nutrient malabsorption. Keto can be used to treat seizures in children, but this is an exception to the rule. Keto may exacerbate heart conditions: Keto isn't great long-term if you have, or are at risk of, heart rhythm problems. A large 2019 study, published by the American College of Cardiology, that involved medical records of nearly 14,000 people reported that people who don't consume many grains, fruits, and starchy vegetables for years at a time, are at a higher risk of developing a heart condition called AFib. Keto may cause nutrient deficiencies: Even if you're otherwise healthy, long-term keto could lead to vitamin B and C deficiencies, since many foods rich in these vitamins - like beans, legumes, and fruit - are also high in carbs. If you're still in a caloric surplus, keto may actually lead you to weight gain. Keto should be treated carefully by those with diabetes: "If you have diabetes and are using diabetes medications to control blood sugar, you should work closely with your physician in order to adjust medications appropriately." Some studies suggest that people with diabetes who go on a ketogenic diet may not need as much or any insulin regulating medication. Keto is a restrictive diet that may be hard to sustain: "The average 'healthy' person probably does not need to follow a keto diet but they could probably benefit from reducing their intake of refined/processed carbohydrates." In a 2004 study of the keto diet, patients found it at times difficult to follow consistently due to its restrictive nature. This has been echoed throughout the literature at large regarding the long-term effectiveness of keto. The ketogenic diet, famous for its touted weight loss benefits, is essentially a low-carb diet. There are many variations of this diet suited to different needs and goals. However, the keto diet doesn't just help with weight loss. Evidence indicates that it has clinical and therapeutic benefits in treating type 2 diabetes and epilepsy. Keto diets are high in healthy fats and protein also tend to be very filling, which can help reduce overeating of empty calories, sweets and junk foods. 4) For most people eating a healthy low-carb diet, it’s easy to consume an appropriate amount of calories, but not too many, since things like sugary drinks, cookies, bread, cereals, ice cream or other desserts and snack bars are off-limits. Often caused by lymph node removal or damage due to cancer treatment, lymphedema occurs because there’s a blockage in the lymphatic system and results in the swelling in leg or arm. A 2017 study involved patients who suffered from obesity and lymphedema and who embarked on a 18-week ketogenic diet. Weight and limb volume was significantly reduced. Polycystic ovary syndrome (PCOS) is the most common endocrine disorder, and it affects women of reproductive age. Symptoms include obesity, hyperinsulinemia and insulin resistance. A pilot study took 11 women through 24 weeks of a low-carbohydrate ketogenic diet (20 grams or less per day).|Rather than relying on counting calories, limiting portion sizes, resorting to extreme exercise or requiring lots of willpower, this low-carb diet takes an entirely different approach to weight loss and health improvements. It works because it changes the very “fuel source” that the body uses to stay energized: namely, from burning glucose (or sugar) to dietary fat, courtesy of keto diet recipes and the keto diet food list items, including high-fat, low-carb foods. Making that switch will place your body in a state of “ketosis,” when your body becomes a fat burner rather than a sugar burner. Fortunately, if you’re new to this type of eating plan, a keto diet for beginners, or keto basics, is surprising simple to follow. 1. Reduce one’s carb intake. 2. Increase your consumption of healthy fats, which help create satiety. 3. Without glucose coursing through your body, it’s now forced to burn fat and produce ketones instead.
If you have something that is a carbohydrate on top of everything else you eat, that will put you over your allowance and you might not get into ketosis. Where most people fail at keto is they go through their day trying to follow the diet, then reach the evening, and realize they didn’t have enough fat and have to drink heavy cream to make up for it. What you should do instead is front load as much of your fat as possible during “breakfast.” For me, that means having four cups of a keto coffee as I work in the morning. That’s usually black tea or coffee with 1 tbsp of butter, ghee, or MCT oil in it. If you want to mix it up a bit, I also like to have mushroom coffee with any of those fats in it, and you can also try MCT oil powder if the normal oil gives you disaster pants. On the other hand, you may be skipping veggies altogether if counting every baby carrot is getting too complicated. But it’s important to get in vegetables (these contain fiber that prevent constipation, a potential side effect of keto) while minding portions and properly counting carbs. Go for nonstarchy options in a rainbow of colors for a variety of nutrients, says Tucci, like leafy greens, cucumber, tomato, broccoli, cauliflower, bell peppers, and asparagus. When it seems as if the sole goal of keto is to drastically cut carbs, the rest can feel like an afterthought. “Reducing your carbohydrate intake is great, but focusing on higher-quality products when budget allows will help improve your health, too,” says Clevenger. That means choosing omega 3-rich foods, like wild salmon, grass-fed, local, or organic meats, and snacking on whole foods rather than processed keto-approved treats. It also means trying to follow a balanced diet as best you can by incorporating as many nutrient-rich fruits and veggies as you can. Many registered dietitians aren’t a fan of keto because it may lead to nutrient deficiencies. You can help avoid these by working with an RD yourself as you follow keto.|Why is the keto diet recommended for people with diabetes or prediabetes? Because the keto diet helps to reduce blood sugar and insulin levels, it is now being used for people with type 2 diabetes and for people with prediabetes to lower their hemoglobin A1C to a healthy level. Who else can benefit from this diet? Women with polycystic ovary syndrome who follow a low-glycemic-index diet - a variation of the keto diet that involves eating based on how foods affect your blood sugar level - have also seen positive results. Recent studies show the diet may treat the following alone or have compounding effects with other medical treatments: migraine headaches, brain tumor/cancer, Alzheimer’s, Parkinson’s disease, mitochondrial disease, Lou Gehrig’s disease (ALS), autism, and traumatic brain injury. Overall, more research is necessary. For the general population, is the keto diet healthy? While this diet has been shown to accelerate weight loss and to improve certain health conditions, it has its fair share of critics. The ketogenic diet makes your body think it is in a state of ketosis, making you burn fat for fuel instead of carbohydrates or protein. What does the research say? The short-term weight loss effects of the ketogenic diet seem promising, but very little information is known on whether or not these effects continue during long-term compliance. In fact, one of the major concerns regarding the diet is its long-term feasibility. Strict dieting regimens that lead to short-term weight loss can eventually lead to increased weight gain once dieters stop following the diet. How safe is the keto diet? As mentioned earlier, the majority of calories in a ketogenic diet originate from fat. This causes many to fear the risks of developing heart complications due to increased consumption of saturated fats and cholesterol. Nevertheless a recent analysis reviewing more than 20 published trials reported there is no significant evidence that consumption of saturated fat increases the risk of heart complications. American Heart Association recommends limiting saturated fat intake to six percent of total caloric intake. This would be about 13 grams of saturated fat for someone consuming 2,000 calories. Strict avoidance of dietary carbohydrates can limit the diversity of an individual’s diet, which may increase the risk of nutrient deficiency. Dietary analysis shows that those consuming a ketogenic diet lack sufficient intake of calcium, vitamin D, phosphorus and magnesium. These nutrients are vital for bone health, and intake below the recommended amount can lead to osteoporosis. Unlike with calorie restriction, keto helps you lose weight by putting your body into ketosis. When you eat minimal carbohydrates, your body produces ketones for energy. Ketones are made in your liver from fatty acids found in food or your own body fat. Therefore, your liver actually burns fat to make ketones. Ketones are used for energy in lieu of carbs. As your body steadily burns fat as a fuel source, you will start to lose weight. You may be wondering if keto can target specific problem areas, such as belly fat. Burning belly fat is high on the priority list for many people. The fat in your belly is visceral fat, which is a dangerous type of fat that lives deep inside the abdomen, encasing your internal organs. Visceral fat is linked to heart disease and type 2 diabetes. Technically, you can’t spot-target fat areas for reduction. Your body decides where weight loss will occur. However, keto may be useful for eliminating stubborn belly fat.
From your brain to your blood cells, glucose is typically the most readily available source of energy. We get glucose from the foods that we eat - whether that’s breads and refined sugars or those found naturally in nature, like fructose from fruits. But to keep the body and brain functioning in times of starvation when carbohydrates weren’t available, the human body can adapt to using ketones, instead of carbs for fuel. While the shift from using glucose to ketones might seem unnatural, your brain actually processes ketones more efficiently than glucose. Your brain is like a luxury car - why put in economy fuel if you can afford premium? But don’t just take our word for it. The keto diet was originally created to treat epilepsy in children, and is still used today in treatment for children and adults with drug-resistant forms of epilepsy. Does the ketogenic diet work? According to the NIH, there is, “no doubt that there is strong supportive evidence that the use of ketogenic diets in weight loss therapy is effective.” In fact they agree that there are many other positive benefits too, like improved mood and protection from cognitive impairment caused by obesity. This myth is a common misnomer in the weight-loss business, as most individuals believe that a keto diet is a solution to all their weight loss issues. There are several seemingly attractive keto plans, but the success factor lies in getting a plan that you’ll follow through with all consistency and dedication. It is a common belief that fruits and vegetables shouldn’t be included in keto diets as they are a good source of carbohydrates. However, fruits and vegetables are a very important source of essential vitamins, fiber and antioxidants. They help reduce the chances of you developing a constipated side effect of keto. A mixture of non-starchy vegetables such as peppers, cucumber, cauliflower, zucchini, and broccoli with low-carb berries such as raspberries, strawberries, and blueberries will suffice. Most persons think of keto diets as an alternative shortcut to weight loss. A path that they could easily walk in and out of whenever they feel like. Fluctuating diets is no way to lose weight if that’s your goal. It would be best if you stuck to your keto diet program or schedule with all the seriousness and dedication you can muster. Going on and off carbs will do you no good in the long run. Keto diet is not a shortcut path on the journey to successful weight loss. You will need to unlearn these common myths about keto if you plan to get the best results and utilize your diets effectively. Also, remember that keto diets aren’t a generic thing that a specific one applies to everybody. It is recommended that you speak to your doctor, dietician, or nutritionist to get the best keto program for you. “As long as carbs stay low enough, which will vary by person but is usually below 50 g a day, one will stay in ketosis,” Kizer says. As a result, you’ll be able to see the effects associated with being in the metabolic state. Who It's Best For This is meant for those who are interested in ketosis but don’t want to be bothered with tracking calories, protein, and fat. Risks to Note The same people who experts say should stay away from keto in general should also avoid this approach, such as pregnant women, people with diabetes who are using insulin or taking hypoglycemic medication, and people with type 1 diabetes who are at risk for ketoacidosis, Kizer says. Lazy keto can also be dangerous if you take it to mean that you sometimes follow a keto diet and sometimes don’t. “Ketosis is all or nothing - you’re either in ketosis or you’re not,” Kizer says.
As with any dietary pattern, the fats don’t have to be animal fats. A study found that a ketogenic diet high in polyunsaturated fats was superior to a saturated fat-rich ketogenic diet by several measures. Getting more plant-based fats from avocados, nuts, seeds, coconut, and olive oil will supply more micronutrients as well as heart-healthy fatty acids. Research on long-term effects of the ketogenic diet are currently lacking, longer-term research studies are in progress. Studying the ketogenic diet for a long time is more difficult than many diets because it is so extreme. Just because the ketogenic diet is trendy doesn’t mean everyone should hop on the bandwagon. There are other dietary patterns that are shown to promote health and a healthy weight, including Mediterranean and vegetarian dietary patterns. And research has demonstrated that some people thrive on lower-fat, higher-carb diets. It’s just a tool in the toolbox that people can implement. Risks to Note Despite the name, this isn’t really keto, Scholl says. With the higher carb intake, you’ll no longer be in ketosis, with your body using fat for energy instead of carbs. The macros with Keto 2.0 make it closer to a moderately low-carb diet, such as the maintenance phase of the Atkins diet, according to Scholl. So the risk is that you’re not actually doing keto and getting into ketosis, which may lead to weight gain, but that said, this might be a nice bridge from higher-carb eating toward more traditional keto approaches. How It Works Is this diet as fun as it sounds? Depends on whom you ask. The macronutrient distribution in the “dirty keto” approach is the same as in the standard keto plan, according to Melissa Nieves, RD, an advisor for HealthyMeals Supreme who is based in Puerto Rico. The big difference is that the source of these macros can come from any kind of food, including highly processed and prepackaged meals.
Try not to compare your weight loss success to someone else's. It depends on how strict you are. If you restrict carbs to below 20 grams, it typically takes 2-3 days to go into ketosis. The most popular choice for a keto breakfast is bacon and eggs. But a lot of people can get tired of not having variety quickly. Try my keto pancakes or low carb yogurt to mix things up and stay within your macros. For week 1 of keto, I recommend keeping it very simple in order to get your body used to running without an influx of carbs. So for this week don't worry about calories, portion sizes or whether you're in ketosis. This week is just about training you to avoid starches and sugars and training your body to run off fat rather than sugar. Every meal does not have to be in balance, but the proportions should be close to these at the end of the day. The effects of maintaining ketosis for long periods of time are unknown. But concerns include the impact on important gut microbes that are likely to be starved of essential fibre required for healthy balance. The potential effect of this on long-term health is still not clear. Most people calling their diet a keto diet are simply following a low or very low carbohydrate diet. Low carbohydrate diets can be helpful, at least in the short term, for some people to lose weight. However, as with the true ketogenic diet, most people can’t stick with a very low carbohydrate diet for long. The latest research shows that it’s the ability to stick to the diet that matters. But it’s worth noting that, as yet, there hasn’t been enough research into the ketogenic diet to support its use in some medical conditions - so people using the diet to treat diabetes or polycystic ovarian syndrome, should consult their doctor before trying it, as it can affect blood sugar levels. Maintaining proper electrolyte balance is important while following a keto diet. Depending on a person’s activity levels, it is recommended that 2 to 7 grams of salt be added to the diet daily. Many people add a cup of high-sodium broth twice a day to meet sodium needs. Would you consider keto a long-term, sustainable diet? A well-formulated ketogenic diet with adequate protein, proper supplements (such as a multivitamin, calcium with vitamin D, phosphorous, and levocarnitine), and regular labs would be sustainable. If people are curious and want to try the keto diet, I recommend working with a registered dietitian who understands what is necessary to successfully follow the diet and who can help monitor their health. Mary Montgomery, MS, RD, CDN, is a pediatric clinical dietitian at the Epilepsy Center at NewYork-Presbyterian/Weill Cornell Medical Center. She specializes in the ketogenic diet for her pediatric patients suffering from epilepsy as well as for adults with epilepsy and cancer. Want more stories like this?

For reasons not entirely understood even today, fueling the body on primarily ketones reduces seizures. However, with the development of anti-seizure medications, few people with epilepsy rely on ketogenic diets today, according to a 2008 paper in the journal Current Treatment Options in Neurology, but some people who don't respond to medications can still benefit. For weight loss, today's keto diets are the descendants of low-carb diets like the Atkins diet, which peaked in popularity in the early 2000s. Both types of diets reject carbs in favor of meatier meals. There is no single blueprint for the keto diet, but plans usually call for eating fewer than 50 grams of carbohydrates a day. Celebrity adherents to the diet include Halle Berry and Kourtney Kardashian. While certain diets are lauded for their dramatic weight loss effects, that doesn't necessarily mean they're good for your heart health. With 1 in every 4 deaths in the U.S. Here, Dr. Elizabeth Klodas, MD, FACC, cardiologist, and founder of Step One Foods, addresses three popular weight-loss diets that could be detrimental to your heart. In conclusion, she shares which diet is the best for both your heart and overall health. Before you go, don't miss 15 Underrated Weight Loss Tips That Actually Work. Worst diets for heart health. The keto diet, and even the paleo and Atkins diets, fall under the same category of diets, according to Klodas. They're all high in animal protein and fat but low in carbohydrates. There are a few points of concern here with these types of diets. First, low-carb diets have been shown to impair vascular function, meaning the arteries can't dilate properly, resulting in insufficient blood flow to the heart, the cardiologist says.|Plus, sugar is often added to make up for a loss of flavor and texture, so some actually have more sugar than full-fat dairy. Resist shredded cheese, too, as it contains a carby potato starch that keeps it from sticking together. Macadamia nuts, pecans, walnuts, almonds, flax seeds, and sunflower seeds. Be careful when eating nuts, as they’re calorie-dense and can easily put you over your carb limit for the day. Cashews, pistachios, and chestnuts are on the higher end for carbs in nuts, and should be avoided. Avocados are low in carbs and have great fat and fiber content; berries are OK since their carb content is negligible; and 1 cup of tomatoes has just 6g of carbs. Fruits in general, dried or otherwise, are forbidden since most have high sugar and carb content. Water, sparkling water, seltzer, black coffee, unsweetened and herbal teas, unsweetened nut milks, wine, light beer, and liquor. Pin it to save for later! 7. Portions Do Matter. 6 above. Even though calories and portions are not the primary focus of a ketogenic lifestyle, they still matter. It’s still possible not to lose weight, or even gain weight, on keto if you consume too much - this would be the case with any diet. The key to remember is that fat is a lever. Fortunately, ketosis inherently reduces hunger and cravings, so you tend to eat less anyway. Many people find that eating low carb foods keeps their portions under control naturally, but if that doesn’t happen for you, you may need to pay attention to them. 8. Eat Only When Hungry. A common question I get is whether you should eat when you are not hungry. Ketosis acts as a natural appetite suppressant, so you may find that you don’t get hungry as often, or not as ravenously so. There is no need to eat when you are not hungry!
Additionally, some patients may feel a little tired in the beginning, while some may have bad breath, nausea, vomiting, constipation, and sleep problems. Is a ketogenic diet healthy? We have solid evidence showing that a ketogenic diet reduces seizures in children, sometimes as effectively as medication. Because of these neuroprotective effects, questions have been raised about the possible benefits for other brain disorders such as Parkinson’s, Alzheimer’s, multiple sclerosis, sleep disorders, autism, and even brain cancer. However, there are no human studies to support recommending ketosis to treat these conditions. Weight loss is the primary reason my patients use the ketogenic diet. Previous research shows good evidence of a faster weight loss when patients go on a ketogenic or very low carbohydrate diet compared to participants on a more traditional low-fat diet, or even a Mediterranean diet. However, that difference in weight loss seems to disappear over time. A ketogenic diet also has been shown to improve blood sugar control for patients with type 2 diabetes, at least in the short term.|For someone eating 2000 calories per day, that translates to around 167g fat, 75-100g protein, and 25-50g carbohydrates. This is key: the total calories you consume are not NEARLY as important as the overall ratio of protein/fat/carbohydrate that you take in. Consuming foods with this macronutrient ratio causes our bodies to burn fat for fuel instead of carbohydrates, meaning it’s a simple (not easy, but simple) way to burn body fat more efficiently. Because of this, the ketogenic diet has been getting a ton of buzz recently for its weight loss benefits. Many people who adopt a ketogenic lifestyle tout easy weight loss from following the protocol, without adding in extra exercise or worrying about total calories. It’s true, you can experience rapid, significant weight loss if you follow this diet correctly, to do this safely, there are other nutritional considerations - more on that soon. WHERE DID KETO COME FROM? The ketogenic diet is the gold standard diet for epilepsy, and research demonstrates that these benefits could actually extend to other neurodegenerative diseases as well. The main difference between the five types of Ketogenic Diets is this macronutrient ratio. All Ketogenic Diets are high in fat, adequate in protein and low in carbohydrates. This combination changes the way energy is used in the body, converting fat into fatty acids and ketones in the liver. When there is an elevated level of ketones in the blood, one is in a state of ketosis, which has a variety of therapeutic benefits for the sick and healthy alike. In addition to the macronutrient ratio, the frequency of eating can influence ketosis. More specifically, a practice called intermittent fasting, which reduces the window of time a person eats throughout the day, can help in obtaining and sustaining ketosis. When the eating window is shortened, the body is forced to access energy from its own fat stores rather than calories directly from the diet. An individualized and structured diet that provides specific meal plans. Foods are weighed and meals should be consumed in their entirety for best results. Pin it to save for later! 7. Portions Do Matter. 6 above. Even though calories and portions are not the primary focus of a ketogenic lifestyle, they still matter. It’s still possible not to lose weight, or even gain weight, on keto if you consume too much - this would be the case with any diet. The key to remember is that fat is a lever. Fortunately, ketosis inherently reduces hunger and cravings, so you tend to eat less anyway. Many people find that eating low carb foods keeps their portions under control naturally, but if that doesn’t happen for you, you may need to pay attention to them. 8. Eat Only When Hungry. A common question I get is whether you should eat when you are not hungry. Ketosis acts as a natural appetite suppressant, so you may find that you don’t get hungry as often, or not as ravenously so. There is no need to eat when you are not hungry!
Since most people following a western diet are not proficient at metabolizing fat optimally, this period allows the body time to become “fat-adapted”, utilizing dietary fat efficiently and effectively. There are a variety of nutritional plans that will enable a ketogenic lifestyle, and flexibility is one of the hallmarks of the diet that make it easy to adopt as a life-long tool to enhance your health. Our nutritionists can help figure out both the short and long-term options best suited for you and your lifestyle. In my 33 years of working with nutrition therapies, none comes close to the remarkable results I’ve seen achieved with ketogenic diets. I’ve had the honor of working with hundreds of people on the diet, which has taken me all over the world where together with The Charlie Foundation we have trained over 200 hospitals in ten countries. The ketogenic diet was used in several major U.S. The main difference between the five types of Ketogenic Diets is this macronutrient ratio. All Ketogenic Diets are high in fat, adequate in protein and low in carbohydrates. This combination changes the way energy is used in the body, converting fat into fatty acids and ketones in the liver.

An individualized and structured diet that provides specific meal plans. Foods are weighed and meals should be consumed in their entirety for best results. It's advertised as a weight-loss wonder, but this eating plan is actually a medical diet that comes with serious risks. In the world of weight-loss diets, low-carbohydrate, high-protein eating plans often grab attention. The Paleo, South Beach, and Atkins diets all fit into that category. They are sometimes referred to as ketogenic or "keto" diets. But a true ketogenic diet is different. Unlike other low-carb diets, which focus on protein, a keto plan centers on fat, which supplies as much as 90% of daily calories. And it's not the type of diet to try as an experiment. Kathy McManus, director of the Department of Nutrition at Harvard-affiliated Brigham and Women's Hospital. How does the keto diet work? Here are the basics of keto: The diet aims to force your body into using a different type of fuel. Instead of relying on sugar (glucose) that comes from carbohydrates (such as grains, legumes, vegetables, and fruits), the keto diet relies on ketone bodies, a type of fuel that the liver produces from stored fat.
In fact, a recent study published in the British Journal of Nutrition concluded that an increase in lycopene consumption is associated with a lower risk of developing cardiovascular disease. Unfamiliar with this fatty food? Ghee is a form of clarified butter that regularly makes an appearance in Indian food as well as on our list of fat-burning keto diet foods. In addition to its abundance of fat, ghee is also high in fat-soluble vitamins such as vitamin A, vitamin E, and vitamin D. You can, of course, buy ghee at the grocery store or you can make your own: The Easiest Way to Make Ghee at Home. These mini cabbages are a winter and fall favorite that you can enjoy all year-round on the ketogenic diet. Brussels sprouts are chock-full of nutrients including vitamin C, vitamin K, folate, and phosphorus, so don't be afraid to dig in. Asparagus is a low-carbohydrate vegetable that you should make an effort to incorporate into your diet, whether you are going keto or not. The stalky green is rich in glutathione, a compound with major cancer-fighting benefits. A study published in the journal Cancers found that glutathione participates in cell protection and regulation. Caffeine-fiends are in luck: coffee is allowed on the ketogenic diet. The bad news? Sugar and milk are both off-limits. If you can't stomach the idea of drinking your coffee black, you can make bulletproof coffee, which is made by adding butter and coconut oil or concentrated MCT oil to your morning brew. Just make sure you're choosing the right keto add-in, because some keto creamers are on our list of 7 Things You Should Never Add to Your Coffee. Protein is part of the keto diet, but it doesn't typically discriminate between lean protein foods and protein sources high in saturated fat such as beef, pork, and bacon. What about fruits and vegetables? All fruits are rich in carbs, but you can have certain fruits (usually berries) in small portions. Vegetables (also rich in carbs) are restricted to leafy greens (such as kale, Swiss chard, spinach), cauliflower, broccoli, Brussels sprouts, asparagus, bell peppers, onions, garlic, mushrooms, cucumber, celery, and summer squashes. A cup of chopped broccoli has about six carbs. A ketogenic diet has numerous risks. Top of the list: it's high in saturated fat. McManus recommends that you keep saturated fats to no more than 7% of your daily calories because of the link to heart disease. And indeed, the keto diet is associated with an increase in "bad" LDL cholesterol, which is also linked to heart disease. Nutrient deficiency. "If you're not eating a wide variety of vegetables, fruits, and grains, you may be at risk for deficiencies in micronutrients, including selenium, magnesium, phosphorus, and vitamins B and C," McManus says.|By following a keto diet plan, you force your body to burn fat, and you don’t switch back and forth, so your body stays in fat-burning mode all the time. Please note that a low carb or Paleo diet could also be a keto diet! If you’re eating a diet with low enough amount of carbohydrates to trigger ketosis, then that diet is technically keto, even if your plan says it’s paleo or low-carb. This is one of the reasons it can be hard to answer the question “what is a keto diet? ”, because the keto diet can be done several different ways. I highly recommend you check out our Paleo diet vs. ’ll help you understand the difference between the two diets better. I still remember when I used to count calories. I was constantly hungry! My salads didn’t satiate me, and toast just made me hungrier! I used to go to sleep hungry and upset because I could never seem to eat less than 1600 calories. Dry wine, champagne, and hard liquor should be enjoyed sparingly. All spices and some sweeteners: Enjoy stevia and sucralose every once in a while. It's a pretty exhaustive list, and probably includes some of your favorites: Bread, rice, pasta, fruit, corn, potatoes, beans, baked goods, sweets, juice, and beer all get the axe. Basically, you have to avoid most sugars and starches. Whole grains like oatmeal don't even make the cut! Almost all fruits: Apples, bananas, oranges, grapes, watermelon, peaches, melon, pineapple, cherries, pears, lemons, limes, grapefruits, plums, mango, and more. Most grains: Wheat, rice, rye, oats, corn, quinoa, barley, millet, bulgur, amaranth, buckwheat, and sprouted grains. Starches: Bread (all of it!), bagels, cereal, pasta, rice, corn, oatmeal, crackers, pizza, popcorn, granola, muesli, flour. There are some work arounds that dieters can still enjoy, like faux tortilla wraps that are made from cheese. Legumes: Black beans, kidney beans, pinto beans, navy beans, soybeans, peas, chickpeas, lentils.|Just avoid pairing this fatty fruit with chips or toast in order to adhere to ketogenic principles-instead, enjoy it as a topping to your salad, baked with an egg inside, or as a side to your morning bacon and eggs.

Walnuts are an excellent source of fat and protein, which makes them a healthy choice for most kinds of meal plans. Their high fat content and zero sugar status make them a must for keto devotees. Another protein-packed pick, almonds are a great choice for keto dieters. The combination of fat, protein, and fiber is an ideal trio when it comes to annihilating hunger and stopping cravings in their tracks.

Lentils, chickpeas, and beans need to be banished from the keto diet. Walk away from starchy vegetables like potatoes, yams, or carrots. Ditch any food that’s been processed. Hotdogs, chips, or junk foods all fall into this category. Sugar and all things nice don’t cut it on the keto diet. Get rid of candy, desserts, and any baked goods. Cast to the side any type of drink that has high sugar content; this also means fruits juices. Most fruit, especially dried fruits like raisins, dates, and banana chips, are not allowed on the keto diet. Certain alcoholic beverages are laden with sugar, so pass on the cocktails or the beers at the party. Traditional low fat “diet” foods do not form part of the high fat keto mantra therefore leave well alone. The keto diet can provide many benefits to specific health conditions as well as general well being. How to tell when you hit Ketosis? There are five variations of the Ketogenic Diet which have been published in medical literature as effective treatments for diseases that have an underlying metabolic dysregulation, such as epilepsy, cancer, and Alzheimer’s. The original Ketogenic Therapy, known as the classic Ketogenic Diet, or classic Keto for short, was designed in 1923 by Dr. Russell Wilder at the Mayo Clinic for the treatment of epilepsy. All Ketogenic Diets are a variation of classic Keto, which is the most strict, seen by it’s ratio of fat to protein and carbs, also called the macronutrient ratio. Classic Keto carries a 4:1 ratio, which means that there are four parts fat for every one part protein and carb. Since fat has a higher caloric content versus protein and carb (fat has 9 calories per gram, while both protein and carb have just 4 calories per gram), 90% of calories come from fat in a classic Ketogenic Diet, while 6% come from protein, and 4% come from carb. However, Dr Atkins knew about ketosis and promoted it. He never measured blood ketone production by his patients, but he did use urine ketone testing strips “for every patient on every visit” - according to Registered Nurse Jackie Eberstein, who worked with Dr Atkins, and as Jimmy Moore reports in Keto Clarity, Dr Atkins later added a machine for analyzing ketones in the breath as well to his clinic. However, many people do call the more modern form of the keto diet (where you eat higher carbs and protein than in the traditional epilepsy studies) a Modified Atkins Diet. How is Paleo different from Keto? In some respects Paleo is very similar to the Keto diet, and if I was going to give a very basic definition of a keto diet, I’d say it’s a lower carb version of Paleo. If you cut out the sweet potatoes, honey, starchy tubers and sugary fruits from Paleo, then you’re left with a pretty healthy keto diet.|The study found that while all vegans experienced a reduced risk of heart conditions and mortality from cardiovascular problems, the risk reductions were more significant in males than in females. Individuals following a vegan diet also tend to have a lower body mass index (BMI) than nonvegans, with research indicating that BMI gets higher as the number of animal foods in the diet increases. Research has also shown that vegans gain less weight than omnivores as they age. A review of 12 studies found that those following a vegetarian or vegan diet for an average of 18 weeks lost about 4.4 pounds (2 kilograms) more than nonvegetarians. Vegans also lost more weight than vegetarians, who ate dairy and eggs. When it comes to the keto diet, the main benefit appears to be rapid weight loss. A 2012 study involving children and adolescents with obesity found that other benefits include reductions in fat mass, waist circumference, and fasting insulin levels. This mechanism has served us for hundreds of years through periods of scarcity or famine. A lack of consistent energy slows our metabolism because our body wants to do one thing: keep us alive. A slowed metabolism is also why it’s hard for people who restrict their intake to continue to lose weight past a certain point or maintain their current weight loss long-term. Moreover, there are some confounding variables worth noting when on a ketogenic diet. First, cutting out an entire food group will consequently reduce your intake. Yes, you can eat more protein and fat, but these nutrients are more satiating and less likely to be overeaten than carbohydrates. To put in simpler terms: you could probably eat 3 bagels before you ate 3 steaks or 3 avocados! Additionally, avoiding carbs may also leave you lacking some key nutrients, like the vitamins and minerals found in fruits and vegetables. Furthermore, the weight loss is probably not permanent. The ketogenic diet may help you (temporarily) lose weight, but the odds of it staying off are slim. There are five variations of the Ketogenic Diet which have been published in medical literature as effective treatments for diseases that have an underlying metabolic dysregulation, such as epilepsy, cancer, and Alzheimer’s.

Targeted ketogenic diet (TKD): This eating plan simply tells you to follow the keto diet BUT allows you to add carbs around workouts. So on the days you exercise, you will be eating carbohydrates. Restricted ketogenic diet (RKD): Designed to treat cancer, this ketogenic meal plan restricts calories as well as carbohydrates. Some studies indicate that calorie restriction and ketosis may help treat cancer. High-protein ketogenic diet (HPKD): This version of the keto diet is often followed by folks who want to preserve their muscle mass like bodybuilders and older people. Rather than protein making up 20 percent of the diet, here it’s 30 percent. Meanwhile, fat goes down to 65 percent of the diet and carbs stay at 5 percent. Vegan ketogenic diet or vegetarian diet: Yes, both are possible. Instead of animal products, plenty of low-carb, nutrient-dense vegan and/or vegetarian foods are included. Nuts, seeds, low-carb fruits and veggies, leafy greens, healthy fats and fermented foods are all excellent choices on a plant-based keto diet.
The keto diet is all about finding the sweet spot of ketosis. However, if it’s a biological process going on inside your body, how can you tell that you’ve hit it? This is where you have two options. Being in ketosis means the levels of ketones will be higher in your body than normal. Therefore to get an accurate result - a breath, urine, or blood sample will do the trick. However, option two is a far simpler. There are people out there who let their state of ketosis take over their diet. To be honest it’s nothing to get hung up over and it’s far better to concentrate your efforts on eating the right foods. Are There Any Side Effects to the Keto Diet? In most cases, the keto diet is considered a safe way to lose weight and reap the benefits. However, in spite of all the good things mentioned, it is possible to experience some mild side effects.|Employ whatever tools or strategies you need to make your life easier while you transition to a new way of eating. Most importantly, check in with your body as you go. Are you sharpest with a weekly carb refeed, or do you do better on a full ketogenic diet? Do you burn out when you dip below 100 grams of carbs per day? There’s a lot of variation within lower-carb diets, and some people feel their best with different styles of eating. Find a good balance that works best for your body. What is Metabolic Flexibility and How Can You Achieve It? If you’re someone that feels like more data is helpful, calculating your macros using a macro calculator can be helpful when you’re starting out. Every body is different, and calculating the exact nutrition you need in your keto diet plan can help you get started on the right track without wondering why your keto journey isn’t hitting your goals. The idea behind this is carbohydrates allow for more intense workouts and more efficient post-workout recovery. Immediately before and after your workouts, you can eat 20 to 30 grams of carbs. Your RDA of carbs is 70 to 80 grams. 2. What Should I Eat on the Targeted Ketogenic Diet? The healthiest way to get your carbs on the targeted keto diet is to consume fruit, dairy, and whole-grain foods. Fruits contain fructose. Dairy contains lactose. Whole grains contain glucose. To get your recommended daily allowance of fat calories, cook your food in vegetable oils that are high in omega-6 linoleic acid. Monounsaturated fats come from nuts, palm oil, olive oil, and avocados. Polyunsaturated fats come from nuts and fish. You can also get protein from nuts and fish as well as red meat and poultry. 3. Will the Targeted Keto Diet Kick Me Out of Ketosis? When you eat any amount of carbs, your blood glucose levels elevate and your body’s ketone production drops.
Though it may seem new to your newsfeed, the ketogenic diet has been around since the 1920s. The low-carbohydrate, high-fat diet gained a foothold when proven to reduce seizures in pediatric patients with epilepsy. While still prescribed for that purpose today, the diet is now touted as a weight loss tool. The keto diet is all about cutting carbs and eating more fat. 5 percent of calories from carbohydrates, including low-carb, non-starchy vegetables and small amounts of leafy greens. The keto diet excludes carb-rich foods like grains, beans, fruits and starchy vegetables. 20 percent of calories from protein, such as meat, eggs and cheese. 75 percent of calories from fat, such as oils, unprocessed nuts, butter and avocado. According to Dietitian Richelle Gomez, MS, RDN, LDN, Northwestern Medicine McHenry Hospital, the ketogenic diet is designed to burn fat by cutting carbs. “Your body turns carbohydrates into glucose for energy,” she explains. Breaking down fats for energy is called ketosis. It’s been around for nearly a century, and has its roots in the medical world: In the 1920s, epilepsy researchers found that increased levels of ketones in their patients resulted in fewer seizures, and the diet is still a widely accepted treatment for epilepsy today. There’s also some evidence that a ketogenic diet has therapeutic potential for a wide array of symptoms and diseases, including cancer, polycystic ovary syndrome, neurological conditions, diabetes, and even acne. So how did it become a trendy weight-loss diet? Though keto has been gaining popularity recently thanks to celebrity endorsements and a wealth of diet-adherent Pinterest recipes, this is not the first time a form of it has gone mainstream. “We have been seeing different variations on the low-carb diet for decades,” says Abbey Sharp, a registered dietician and nutrition blogger. “The Atkins diet and the Dukan diet are two variations of a ketogenic diet.
There is no one standard ketogenic diet, and different ratios of nutrients have been used in so-called keto diets. All have in common the reduction of carbohydrates and an increase in fat along with a moderate amount of protein. The reduction in carbohydrates deprives the body of glucose and causes a metabolic state known as ketosis, due to the accumulation of molecules known as ketones in the bloodstream. Ketones consist of acetoacetate, acetone, and beta-hydroxybutyrate and form in the liver from long- and medium-chain fatty acids when the body burns stored fat for energy after glucose is depleted or in situations in which there is inadequate insulin present for glucose to be used as energy. In addition to seizure disorders, ketogenic diets have been tested in the management of some people with other conditions including diabetes, cancer, polycystic ovary syndrome, and Alzheimer's disease. Further, the "keto diet" has gained attention as a potential weight loss tool. Its proponents argue that a carefully controlled ketogenic diet can avoid the dangers of ketoacidosis and be an effective way to lose weight. And basically ketones can stand in as glucose for fuel when we’re not eating carbs. Just to break it down again: On the high-carb diet you eat carbs like pasta or bread, your glucose levels rise, the pancreas secretes insulin and then the insulin moves the glucose into our cells to power our body. On the keto diet, a person eats fats like steak and eggs. The glucose and insulin levels in the body fall. The liver converts the fat into ketones and then the ketones fuel the cells and tissues of the body. You’re making the body find a way to use fat as a source of fuel. Is there another way to get the body into ketosis? Starvation. When you fast - think about it again, our bodies don’t have glucose stored up anywhere. When you’re not eating, it has to turn to fat stores to start to get energy to keep going. Ketosis is a natural metabolic state in which the body burns fat rather than carbs. ’s the primary reason why people start it,” says Los Angeles-based Franziska Spritzler, RD, founder of Low Carb Dietitian. There are some other researched benefits beyond weight loss, including possibly acting as a mood stabilizer in those with bipolar disorder (per a very small study in Neurocase) and, more rigorously studied, lessening epileptic seizures (according to a study published in May 2016 in Epilepsy & Behavior). But not everyone’s a fan. “For most people, going keto means jumping on the diet-of-the-moment bandwagon,” says Jackie Newgent, RDN, a culinary nutritionist in New York City and the author of The All-Natural Diabetes Cookbook. “For most, it’s a fad diet that will offer temporary results.” That runs counter to Newgent’s usual advice to find an eating plan you can follow for a lifetime. She also worries that reducing carbs as much as the original keto diet calls for will cut out nutrient-rich foods, like whole grains, certain veggies, and fruits.|Liver problems. With so much fat to metabolize, the diet could make any existing liver conditions worse. Kidney problems. The kidneys help metabolize protein, and McManus says the keto diet may overload them. Constipation. The keto diet is low in fibrous foods like grains and legumes. Fuzzy thinking and mood swings. Those risks add up - so make sure that you talk to a doctor and a registered dietitian before ever attempting a ketogenic diet. What about the other diets? The popular low-carb diets (such as Atkins or Paleo) modify a true keto diet. But they come with the same risks if you overdo it on fats and proteins and lay off the carbs. So why do people follow the diets? McManus says. Theories about short-term low-carb diet success include lower appetite because fat burns slower than carbs.

No content on this site, regardless of date, should ever be used as a substitute for direct medical advice from your doctor or other qualified clinician. Although there are a few exceptions, nonstarchy vegetables aren't rich sources of fermentable, prebiotic fiber. And what about saturated fats-is the ketogenic diet really the "bacon and butter" diet? As with any dietary pattern, the fats don't have to be animal fats. A 2004 study found that a ketogenic diet high in polyunsaturated fats was superior to a saturated fat-rich ketogenic diet by several measures.16 Getting more plant-based fats from avocados, nuts, seeds, coconut, and olive oil will supply more micronutrients as well as heart-healthy fatty acids. One safety concern about this diet is nondiabetic ketoacidosis. While this condition is rarely caused by low-carbohydrate diets, patients with comorbid conditions who experience an illness-such as the seasonal flu-or other stressors while following the ketogenic diet are at higher risk.17 In addition, Haggerty says the rigidity of the ketogenic diet easily can become obsessive and lead to disordered eating behaviors. Ayesta says that while research on long-term effects of the ketogenic diet currently are lacking, longer-term research studies are in progress. Unfortunately, keto diets are probably more prone than many others to end with weight regain because they can be hard to stick to in the long run, Carson said. And being in ketosis for more than a few weeks might not be best for overall health, she said. Some of this is genetically determined: The extent to which dietary fats and cholesterol translate to increased levels of blood cholesterol (which are associated with heart disease) is partly individual, Carson said. Ketogenic diets also tend to cause more calcium to be lost in the urine, Carson said, which can lead to a decrease in bone density over time and increase the risk of osteoporosis. The AHA recommends eating a variety of fruits, vegetables, whole grains, low-fat dairy, skinless poultry and non-fried fish, nuts and legumes, and limiting red meat, saturated fat and sweets for a heart-healthy diet. Majumdar said. In the case of keto diets, putting the kibosh on fruits, many veggies and whole grains means that people don't end up consuming much fiber. The AHA also recommends at least 150 minutes of moderate exercise a week for heart health. Weight loss and maintenance might take a lot more exercise than that, Carson said, which could be a problem for those on ketogenic diets.
But the body can also burn its own fat stores as well as ketones, which the liver produces as a by-product of fat metabolism. Ketones are a natural source of caloric energy just as glucose is. But there’s a key difference here. The body’s sustained use of ketones and fat (which go hand in hand) doesn’t impose the same inflammatory and oxidative burden as we experience when we’re continually carb (glucose) dependent, which is one reason why keto confers so many benefits to overall health. The technical meaning of ketosis is the metabolic state in which your body accumulates ketones faster than they’re being burned. When we’re fat-adapted (a.k.a. ’re able to enjoy the benefits of burning fat and ketones as first-rung fuel sources. However, when we’re in ketosis without being keto-adapted (e.g. on a crash diet), we’re likely to excrete these ketones in our urine and breath instead of burning them for energy, which means we’re still left carb-dependent. Even after you have finished with doing keto, there is no point going back to your previous - presumably unhealthy - diet. Try keeping at least some of the healthy aspects of your keto diet, like the increased fruit/veg/nut intake, post-keto, too. Can you work out on a keto diet? Thinking about joining the gym? PureGym has over 250 units all across the UK and you won't need a contact either when you sign up - leave anytime if you change your mind. Students save even more on fixed term memberships: up to 30% off. Add more healthy fats to your shakes with Bulk Powders' Medium Chain Triglycerides powder. Does keto diet make you weaker/sleepier? Obviously, if you find yourself feeling fatigued and weak, consider that keto may not be for you, or at least look again at how you're trying to follow a keto diet. Simon does work for a company that sells supplements but there is no evidence that they are bad for you.
It’s all the rage. The internet is filled with stories of how everyone from movie stars to ordinary people have shed stubborn pounds with the ketogenic diet. Some suggest that this eating pattern also may be helpful for managing diabetes and warding off Alzheimer’s disease. So, is it a miracle diet or just the latest fad? The ketogenic diet is a high fat, moderate protein, low carbohydrate eating pattern, which differs from general, healthful eating recommendations. Many nutrient-rich foods are sources of carbohydrates, including fruits, vegetables, whole grains, milk and yogurt. On a keto diet, carbs from all sources are severely restricted. With the goal of keeping carbs below 50 grams per day, keto dieters often consume no breads, grains or cereals. And, even fruits and vegetables are limited because they, too, contain carbs. For most people, the keto diet requires making big shifts in how they usually eat. Why does the Keto diet restrict carbs? Carbs are the main source of energy for our body. Alcohol: Alcoholic beverages are high in carbs, which can take your body out of ketosis. Sugar-free diet foods: These products can be high in sugar alcohols, which affect ketone levels. They’re highly processed, too. FDA authorized at home saliva self-collection testing kit for COVID-19. No waiting in line or uncomfortable swabs. Butter and cream: Products of grass-fed animals, if possible. Healthy oils: Mainly extra virgin olive oil, but coconut and avocado oil are ok, too. In keto and most healthy diets, it’s best to base your meals on whole, one-ingredient foods. To learn more about keto-friendly, low-carb foods, check out this list: Ketogenic diet foods - what to eat. Always try to rotate your vegetables and meats to reduce boredom and maximize your nutritional intake. You can eat a variety of delicious and nutritious meals when following a ketogenic diet plan. Keto Snacks to Enjoy! As with any dietary plan, you might get hungry between meals. This version of the diet allows for the lowest amount of carbs (hence being the strictest). According to the Practical Neurology study, 90 percent of daily calories come from fat, 6 percent from protein, and just 4 percent from carbs. Risks to Note The most common side effects among children who followed the diet were constipation, weight loss, and growth problems or anorexia, found the Practical Neurology study. The growth problems among children may be the result of limited protein intake, Spritzler says. There’s also a risk for developing hypercalciuria (high calcium levels in urine), kidney stones, and low blood sugar. Even though the bulk of research has been on children, adults may experience the same issues - plus possibly high cholesterol, though levels should drop once you quit the diet and start eating normally again. Unsurprisingly, this strict version of keto also seems to be the toughest one to stick to: Research shows that the modified versions of the diet have lower drop-out rates.|Certain studies suggest that keto diets may “starve” cancer cells. A highly processed, pro-inflammatory, low-nutrient foods can feed cancer cells causing them to proliferate. What’s the connection between high-sugar consumption and cancer? The regular cells found in our bodies are able to use fat for energy, but it’s believed that cancer cells cannot metabolically shift to use fat rather than glucose. There are several medical studies - such as two conducted by the Department of Radiation Oncology at the Holden Comprehensive Cancer Center for the University of Iowa, and the National Institutes of Health’s National Institute of Neurological Disorders and Stroke, for example - that show the ketogenic diet is an effective treatment for cancer and other serious health problems. Therefore, a keto diet that eliminates excess refined sugar and other processed carbohydrates may be effective in reducing or fighting cancer. It’s not a coincidence that some of the best cancer-fighting foods are on the keto diet food list. Over the past century, ketogenic diets have also been used as natural remedies to treat and even help reverse neurological disorders and cognitive impairments, including epilepsy, Alzheimer’s symptoms, manic depression and anxiety. There are many other eating plans for weight loss that are not as restrictive, are more sustainable, and have more research behind them. Brissette recommends the Mediterranean diet (which was named the best diet to try in 2019) as “one fantastic example of a way of eating that’s been tried and tested over many generations and has been consistently shown to promote longevity and reduce the risk of chronic disease.” The best part? It promotes a balanced plate of healthy, delicious foods-carbs included. If you decide to give keto a try, it’s important to include plenty of minimally processed whole foods, such as low-carb vegetables, plant-based fats such as avocado, olive oil, and nuts, and lean proteins such as fish and poultry. As with any major dietary change, it’s best to follow it under the care of a registered dietitian nutritionist or doctor. Like what you just read? You’ll love our magazine! Go here to subscribe.

Every January, we’re told that detoxes, diets, and a new gym membership are the key to a successful new year. It seems as though everyone’s trying to shave off the pounds as quickly as possible, and whatever diet can promise fast weight loss is the one they’re willing to try. Enter: the ketogenic diet. The ketogenic (often abbreviated to just “keto”) diet promises health benefits from weight loss to increased mental focus. But is it backed by science? Should you jump on the bandwagon or steer clear? What is the ketogenic diet? The ketogenic diet consists of an eating pattern that’s high in fat, moderate in protein and low in carbohydrates. It’s typically rich in foods like eggs, meats, nuts, butters, cheeses, seeds, oils and few low-carb green vegetables. It does not allow fruits, most vegetables, grains, potatoes, sweets, or other carb-rich foods. One common distribution is eating 5% of total calories from carbs, 20% from protein, and 75% from fat. It’s all the rage. The internet is filled with stories of how everyone from movie stars to ordinary people have shed stubborn pounds with the ketogenic diet. Some suggest that this eating pattern also may be helpful for managing diabetes and warding off Alzheimer’s disease. So, is it a miracle diet or just the latest fad? The ketogenic diet is a high fat, moderate protein, low carbohydrate eating pattern, which differs from general, healthful eating recommendations. Many nutrient-rich foods are sources of carbohydrates, including fruits, vegetables, whole grains, milk and yogurt. On a keto diet, carbs from all sources are severely restricted. With the goal of keeping carbs below 50 grams per day, keto dieters often consume no breads, grains or cereals. And, even fruits and vegetables are limited because they, too, contain carbs. For most people, the keto diet requires making big shifts in how they usually eat. Why does the Keto diet restrict carbs? Carbs are the main source of energy for our body. It should be noted that the keto diet may not always trigger weight loss, especially if you already have a low body fat percentage. 4 Reasons Why You Should Follow a Keto Diet? Weight loss isn’t the only reason to follow a ketogenic diet. Let’s look at some of the other benefits. This is why, despite information that states a certain amount of glucose is needed per day for optimal brain function, a keto diet can actually support cognitive function. In fact, some people report improved focus, concentration and mental alertness when they enter ketosis. A high-carb diet (especially when it comes to dairy products and refined sugar) has been shown to trigger sebum (oil) production in the skin. Removing sugar from your diet may also support skin health. Since high fat foods are also richer and more satiating than carbs, you’ll also feel full with smaller portions. In order for the keto diet to work, you’ll need to know if you’re in ketosis or not. That means two-thirds experienced no symptoms at all. Important: For people who do experience the keto-flu, it's most likely you'll notice them during the first 24 to 48 hours of starting the keto diet, says Keatley. On average symptoms will last between a few days to a week. However, in rare cases, symptoms can last up to a month. See a doctor if you are still feeling under the weather after a week or two of starting the diet. The good news is that there are measures you can take before and during keto to avoid and treat keto flu symptoms. Going keto puts you at an increased risk of dehydration. That's because you may need to go to the bathroom more as your body burns ketones instead of carbs. Even being mildly dehydrated will cause or exacerbate keto flu symptoms like fatigue and dizziness, says Shemek. Therefore, it's important to drink plenty of water throughout to replenish lost fluids. Quick tip: An easy way to check on your hydration levels is to check the color of your urine.

The ketogenic diet, or keto diet plan, is a specific type of low carb diet that is focused on a specific ratio of macronutrients, or macros, with a goal of reaching a state called ketosis. Macronutrients are fat, protein, and carbohydrates. The ketogenic diet is generally 70% fat, 25% protein and 5% carbohydrates. Learn more about how macros work here. Ketosis is a metabolic state in which the body burns fat for fuel instead of carbohydrates. It’s very effective for weight loss, energy and mental clarity. Ketosis is the primary goal of the keto diet plan. We achieve it by severely limiting carbohydrate intake, not calories, but calories are often restricted as a byproduct. In the absence of carbs, the body switches to burning fat for fuel. Signs of ketosis include increased energy and focus, decreased appetite, and changes in smell of breath or urine. You can test yourself for ketosis using ketone test strips (use code WHOLESOME for 15% off!), or a blood monitor if you want to be super accurate (not usually necessary). If you take in less energy than you need, you’ll lose body fat. Ketogenic diets do affect metabolism, the levels of certain metabolic hormones (notably, keto is a low-insulin-producing diet), and appetite, but the basic effect of energy intake is still the same. Can you have cheat days on keto? “Cheat meals”-which I take to mean eating foods like desserts, bakery items, pizza, and the like-will quickly put you over your carb allotment for the day. Accordingly, your liver will stop producing ketones and you’ll get “kicked out” of ketosis. You can’t “cheat” and stay in ketosis all the time. On the other hand, you might not care about being in constant ketosis. If you do get kicked out of ketosis, you can get right back in with 24-48 hours of low-carb eating, especially if you pair it with exercise and/or intermittent fasting. In any case, I’d encourage you to rethink the whole cheating mentality. When those snack cravings hit, make sure you reach for something that is keto-friendly, so as to maintain the state of ketosis achieved through your regular meals. When dining out, it’s usually pretty easy to make most restaurant meals keto-friendly. Most restaurants feature meat or fish-based dishes. Order one of these plates and substitute any high-carb side dishes for vegetables. Egg-based meals, such as omelets or eggs and bacon, are also a great choice. They’re not just good for breakfast-they can be dinner, too! Another keto favorite is the bun-less burger. Try swapping a side of fries for vegetables and adding avocado, bacon, or extra cheese to the burger. At Mexican restaurants, you can eat any type of meat on the menu. You can also add extra cheeses, salsa, guacamole, or sour cream. For dessert, try a mixed cheese place or berries and cream. Keto can help you lose weight and make some positive changes to your life. The high-fat, low-carb diet has gained a lot of popularity in recent years, creating an entire community of keto-praising eaters. But the body can also burn its own fat stores as well as ketones, which the liver produces as a by-product of fat metabolism. Ketones are a natural source of caloric energy just as glucose is. But there’s a key difference here. The body’s sustained use of ketones and fat (which go hand in hand) doesn’t impose the same inflammatory and oxidative burden as we experience when we’re continually carb (glucose) dependent, which is one reason why keto confers so many benefits to overall health. The technical meaning of ketosis is the metabolic state in which your body accumulates ketones faster than they’re being burned. When we’re fat-adapted (a.k.a. ’re able to enjoy the benefits of burning fat and ketones as first-rung fuel sources. However, when we’re in ketosis without being keto-adapted (e.g. on a crash diet), we’re likely to excrete these ketones in our urine and breath instead of burning them for energy, which means we’re still left carb-dependent. “Both alcoholic ketoacidosis and diabetic ketoacidosis create medical emergencies due to the rapid change in the body’s acid-base balance,” Dr. Gonzalez-Campoy says. Common complications of diabetic ketoacidosis include very low blood sugar, or hypoglycemia, and swelling of the brain (cerebral edema). As such, when a person is in ketoacidosis, there is such a high level of ketones produced that can push a person into cardiac arrest (heart attack) or kidney failure. Hence, the very important reason for taking occasional keto breaks go give your body a bit more nourishing carbs. The ketogenic diet was originally formulated by doctors to help treat people with epilepsy, and it was found especially effective in children who didn’t respond to medication.1,2 Indeed, the keto diet has been found to reduce the frequency and intensity of seizures, which are common complications of this condition. This high fat/low carb diet may also help improve certain other neurological disorders like Alzheimer’s disease and Parkinson’s disease,3 according to the Epilepsy Foundation. This is the most important! For a low carb diet, aim for under 50g net carbs per day, though some variations limit to somewhere between 50-100g per day (mostly if you are more active). Get the carb limit down and you’re most of the way there! Limit protein intake. A keto diet or low carb diet is not a high protein diet! Low carb is generally higher in protein than keto, but be careful with both. High protein diets can stress the kidneys, and besides, excess protein converts to glucose. Make your protein intake a goal to meet each day, but more than that is not better. Use fat as a lever. We’ve been taught to fear fat, but don’t! Both keto and low carb are high fat diets. Fat is our source of energy as well as satiety. The key to understand, though, is that fat is a lever on a low carb or keto diet. Carbs and protein stay constant, and fat is the one you increase or decrease (push the lever up or down) to gain or lose weight, respectively.
Keto can be used to treat seizures in children, but this is an exception to the rule. Keto may exacerbate heart conditions: Keto isn't great long-term if you have, or are at risk of, heart rhythm problems. A large 2019 study, published by the American College of Cardiology, that involved medical records of nearly 14,000 people reported that people who don't consume many grains, fruits, and starchy vegetables for years at a time, are at a higher risk of developing a heart condition called AFib. Keto may cause nutrient deficiencies: Even if you're otherwise healthy, long-term keto could lead to vitamin B and C deficiencies, since many foods rich in these vitamins - like beans, legumes, and fruit - are also high in carbs. If you're still in a caloric surplus, keto may actually lead you to weight gain. Keto should be treated carefully by those with diabetes: "If you have diabetes and are using diabetes medications to control blood sugar, you should work closely with your physician in order to adjust medications appropriately." Some studies suggest that people with diabetes who go on a ketogenic diet may not need as much or any insulin regulating medication. Keto is a restrictive diet that may be hard to sustain: "The average 'healthy' person probably does not need to follow a keto diet but they could probably benefit from reducing their intake of refined/processed carbohydrates." In a 2004 study of the keto diet, patients found it at times difficult to follow consistently due to its restrictive nature. This has been echoed throughout the literature at large regarding the long-term effectiveness of keto. The ketogenic diet, famous for its touted weight loss benefits, is essentially a low-carb diet. There are many variations of this diet suited to different needs and goals. However, the keto diet doesn't just help with weight loss. Evidence indicates that it has clinical and therapeutic benefits in treating type 2 diabetes and epilepsy. The main difference between the five types of Ketogenic Diets is this macronutrient ratio. All Ketogenic Diets are high in fat, adequate in protein and low in carbohydrates. This combination changes the way energy is used in the body, converting fat into fatty acids and ketones in the liver. When there is an elevated level of ketones in the blood, one is in a state of ketosis, which has a variety of therapeutic benefits for the sick and healthy alike. In addition to the macronutrient ratio, the frequency of eating can influence ketosis. More specifically, a practice called intermittent fasting, which reduces the window of time a person eats throughout the day, can help in obtaining and sustaining ketosis. When the eating window is shortened, the body is forced to access energy from its own fat stores rather than calories directly from the diet. An individualized and structured diet that provides specific meal plans. Foods are weighed and meals should be consumed in their entirety for best results. Although there are a few exceptions, nonstarchy vegetables aren't rich sources of fermentable, prebiotic fiber. And what about saturated fats-is the ketogenic diet really the "bacon and butter" diet? As with any dietary pattern, the fats don't have to be animal fats. A 2004 study found that a ketogenic diet high in polyunsaturated fats was superior to a saturated fat-rich ketogenic diet by several measures.16 Getting more plant-based fats from avocados, nuts, seeds, coconut, and olive oil will supply more micronutrients as well as heart-healthy fatty acids. One safety concern about this diet is nondiabetic ketoacidosis. While this condition is rarely caused by low-carbohydrate diets, patients with comorbid conditions who experience an illness-such as the seasonal flu-or other stressors while following the ketogenic diet are at higher risk.17 In addition, Haggerty says the rigidity of the ketogenic diet easily can become obsessive and lead to disordered eating behaviors. Ayesta says that while research on long-term effects of the ketogenic diet currently are lacking, longer-term research studies are in progress. Research findings on the benefits of the keto diet for these health conditions are extremely limited. Studies on effectiveness of the keto diet were conducted with small groups of people. And, most of the research about Alzheimer’s disease relies on research done on lab animals. To fully assess the safety of this eating pattern, more research is needed. Plus, studies must be done on the long-term health effects of the keto diet. Body mass index and individual metabolic rates impact how quickly different individuals produce ketones. This means that on the keto diet, some people lose weight more slowly than others - even if they are following the same exact keto diet plan. For this group of people, the keto diet can be frustrating and may impact their motivation for making healthy dietary changes. Plus, many people are not able to stick with the keto diet and gain back the weight after returning to their previous pattern of eating. The ketogenic diet is quite restrictive. Research supports this eating pattern for epilepsy when managed along with a health care team, since its treatment can be very complex. However, with regards to the keto diet as a tool for weight loss and other health benefits, the jury is still out. For a personalized weight management plan that meets your individual needs, consult a registered dietitian nutritionist. An RDN can create a personalized weight loss program based on your unique health and nutrition needs and goals. To find a dietitian in your area, search the Academy's Find an Expert database. All meals should be planned in advance, evaluating the nutritional value of each of them. It is important not to deprive your body of fiber. Fiber is extremely important for intestinal health and can help you get into ketosis without experiencing symptoms of keto flu. If you can’t rigidly track your carb intake, you can try a gradual elimination method. Remove onethe source of carbohydrates from your diet every week. 1. Remove all desserts and sweet snacks such as cakes, pastries, and chocolate bars. 2. The third week is the time to say goodbye to starchy foods like pasta, pizza and packaged snacks. 3. Remove all bread, rolls and starchy vegetables. 4. By Week 5 you are probably down to 50 g of carbs a day. If you want to restrict carbohydrates further, then cut out fruit and sauces that contain carbs. Looking for a way to break the vicious cycle of weight loss and tone up all the jiggly parts?
While fat reigns supreme on the diet, don’t just turn to bacon, cheese, and cream. When choosing your fats, aim to include more anti-inflammatory omega-3s, particularly EPA and DHA, the type that are found in salmon, sardines, oysters, herring, and mussels, says Clevenger. Other healthy fats are a good choice, too; if you haven’t stocked up on avocado, olive oil, and seeds such as chia seeds and flaxseed, definitely do. They’re not only keto friendly - they also offer healthy polyunsaturated and monounsaturated fat that your body needs to perform at its best. With people consuming more sodium than ever in a diet rich in processed food, you’re probably not used to hearing the call to eat more salt. But on keto, it’s necessary. Not only does the clearance of ketones cause the body to lose sodium, but you may be getting much less table salt (which is comprised of 40 percent sodium and 60 percent chloride) now that you’ve kicked out the top source of salt in the standard American diet: packaged, processed foods, including bread, chips, crackers, and cookies. For example, instead of getting healthy fats and low carbs from almonds, you can hit your macro amounts with BBQ pork rinds instead. “The main point of dirty keto is that, since the macronutrient amounts it follows support a ketogenic state, it doesn’t matter where those macros come from,” she says. Who It's Best For This variation is for those who need a high level of convenience and lack the time or interest for cooking and meal prep, Nieves says. This may also be the easiest route to follow for those just getting into keto, she adds, since you can stick to keto even when traveling or dealing with a busy schedule - you just need to read package labels carefully rather than going deep into meal planning. Risks to Note Although it does sound fun to get dirty, Nieves cautions that too many ultraprocessed foods - which have additives like sugar, preservatives, and artificial flavors - can lead to nutritional deficiencies over time, and load you up with too much sodium and unhealthy fats. Losing 0.5-1 pound per week is generally a reasonable, sustainable goal on any diet, but your pace depends on many factors. Depending on how much energy (calories) you take in, you can lose, maintain, or even gain weight on keto. The usual rules of weight loss apply-namely that you have to be using more energy than you’re consuming, and the size of the caloric deficit correlates (imperfectly) with the rate of weight loss. However, keto diets may be advantageous for weight loss due to their noted appetite-suppressing effects and favorable hormonal impacts, particularly in keeping insulin production low. Keto diets are also protein-sparing, meaning you are less apt to lose lean muscle tissue alongside fat, provided you consume adequate protein. Can you do keto while pregnant? Pregnant women need ample calories, nutrients, and protein. While some women do choose to stay keto during pregnancy, others find they feel better when they increase their carb intake. All pregnant and breastfeeding women should consult their doctor with questions or before making major dietary changes. How to get fiber on keto? Keto dieters get their fiber from the plants they consume. Fiber’s most important role is to provide fermentable “food” for our gut microbiota. Keto-friendly items like nuts, cruciferous vegetables, and avocado all deliver healthy doses of fermentable fiber for the gut. Individuals who wish to increase their fiber intake can consider adding prebiotic fiber supplements or supplementing with inulin or raw potato starch. If constipation is your concern, check whether you’re dehydrated or lacking magnesium. Does keto cause diarrhea? Any major dietary shift can cause gastrointestinal symptoms like diarrhea, bloating, or constipation. Usually, these effects are short-lived and resolve on their own within a couple weeks of starting a new diet. Keto doesn’t seem to be especially notorious for causing disaster pants. Most people transition with no issues. The clearer the color, the more hydrated you are. Eating keto-friendly foods rich in fiber can help keep digestive issues like constipation at bay. Fiber promotes a healthy gut by providing bulk and water to your stools, making them easier to pass. Adults should aim to consume at least 25-30 grams of fiber per day. This can be difficult to achieve while going keto as high-fiber foods like whole grains, fruits, and starchy vegetables are limited. While you only have 50 grams of carbohydrates a day on keto, it's important to make sure these carbs count, says Keatley. Not only are you using the bathroom more on keto, but you're going to excrete sodium and potassium through your urine, which are two electrolytes essential for staying hydrated. Depending on the type of exercise you are doing, the activity can exacerbate keto-flu symptoms like fatigue and digestive issues. That's because our bodies are used to pulling energy from carbohydrates during an intense activity like HITT workouts or running, says Keatley. While you're transitioning to ketosis, opt for low to moderate activities like walking or leisurely biking as your body adjusts to a new fuel source. This may help you avoid uncomfortable symptoms associated with the keto-flu, like digestive issues. Consider starting with a less intense moderate- to low-carb diet or making small keto-friendly swaps to your normal meals. The keto-flu is a natural response to switching your primary energy source from carbs to fats. Not everyone will experience keto-flu symptoms, but those that do usually experience them in the first few days of starting the diet and begin to feel better within a week. The keto diet is not for everyone and can cause health issues, like nutrient deficiencies, if it's not done properly. For this reason, consider consulting a registered dietitian or health professional before going keto. The ketogenic diet is increasingly used to treat metabolic disorder. Because maintaining a ketogenic diet reduces blood sugar levels, it’s a natural strategy for treating diabetes and even potentially reversing pre-diabetes. More research is underway to illuminate the effectiveness of keto for those with metabolic disorders. In cancer patients, a keto diet preserves lean mass and causes fat loss. Many researchers are exploring the use of ketogenic diets in preventing and treating cancer, although results are very preliminary. Being keto-adapted has several advantages for anyone interested in physical performance. It increases energy efficiency. It also spares glycogen. Glycogen is high-octane fuel for intense efforts. We store it in the muscles and liver, but only about 2400 calories-worth-enough for a couple hours of intense activity at most. Once it’s gone, we have to carb up to replenish it. Keto-adaptation allows us to do more work using fat and ketones for fuel, thereby saving glycogen for when we really need it. Since even the leanest among us carry tens of thousands of calories of body fat, our energy stores become virtually limitless on a ketogenic diet.
