I’m following the ketogenic diet and I find it very easy, pleasant and varied. I can even say that my diet today is more varied than the previous one. I do not intend to leave this diet and I cannot really see why. My initial focus was not to lose weight, I’ve always been lean, but to feel better, well disposed. And I got it! I am very pleased, I have read a lot about it (including scientific literature) and I have influenced other people who need to lose weight or improve some aspects of their health. But from the beginning I went on my own way, without the help of a nutritionist because I did not want to suffer the influence of others’ ideas.

These are just a few samples of what a ketogenic diet menu looks like. As mentioned above, it comes down to eating some protein, adding as much fat as you like (within calorie limits) and choosing low carb veggies to round out the meal. Of course, you can't consume whole sticks of butter and expect to lose weight, but if you aren't trying to lose weight, eating enough saturated fat and adequate protein is a very good way to kill hunger.
And although in the short term, ketogenic diets seem safe for healthy people, we also lack long-term data on the diet, so it’s hard to confirm long-term safety with certainty. Complications seen with kids maintaining a ketogenic diet for epilepsy, for example, included kidney stones, constipation, gastrointestinal issues, pancreatitis, and vitamin D and calcium deficiencies.
“One of the best meal planning tips I’ve ever received is to structure breakfast and lunch so that you don’t have to think too much about it,” says Emily Bartlett, co-founder of Real Plans. “If you’re okay with repetition, it’s ideal to have a simple selection of recipes for breakfast—including some that can be taken on the go. For lunch, go ahead and use your leftovers with a fresh green salad, and be sure to include a dressing that you really love.”
Around this time, Bernarr Macfadden, an American exponent of physical culture, popularised the use of fasting to restore health. His disciple, the osteopathic physician Dr. Hugh William Conklin of Battle Creek, Michigan, began to treat his epilepsy patients by recommending fasting. Conklin conjectured that epileptic seizures were caused when a toxin, secreted from the Peyer's patches in the intestines, was discharged into the bloodstream. He recommended a fast lasting 18 to 25 days to allow this toxin to dissipate. Conklin probably treated hundreds of epilepsy patients with his "water diet" and boasted of a 90% cure rate in children, falling to 50% in adults. Later analysis of Conklin's case records showed 20% of his patients achieved freedom from seizures and 50% had some improvement.[10]

Of course, one of the biggest benefits of the keto diet—aside from the weight-loss results many see—is the creativity reboot it can give your meals. A lot of healthy foods are banned because of their high carb count, so following the keto diet forced me to experiment with other ingredients, like cauliflower rice and tuna. Since I'm a creature of habit during the day, dinner was the time to play, and the recipes that Green Chef delivered really pushed my husband and me out of our comfort zones. One of our favorite discoveries? Shirataki noodles, a zero-carb Japanese noodle made from yam husks. They work perfectly as a pasta alternative. We enjoyed them in this Pasta with Italian Sausage recipe, but since the noodles easily take on the flavor of the ingredients they're paired with, you could sub them into any favorite pasta dish.


Absolutely nothing jumps out as the cause of the (insert word that rhymes with fall but begins with "st" instead of "f") . I even went full-nerd and did correlation analysis on about 15 measures, and the highest I got on correlation was 0.4, for deficit (although this was for the raw data, not a smoothed out trend). But the last two weeks of it, I ate near maintenance, and even had a couple 150 carb gram days, to try to jostle my metabolism. Then I went straight back to strict keto and a calorie deficit. This seems to have not only ended my (insert word that rhymes with fall but begins with "st" instead of "f"), but accelerated my weight loss.

There are theoretically no restrictions on where the ketogenic diet might be used, and it can cost less than modern anticonvulsants. However, fasting and dietary changes are affected by religious and cultural issues. A culture where food is often prepared by grandparents or hired help means more people must be educated about the diet. When families dine together, sharing the same meal, it can be difficult to separate the child's meal. In many countries, food labelling is not mandatory so calculating the proportions of fat, protein and carbohydrate is difficult. In some countries, it may be hard to find sugar-free forms of medicines and supplements, to purchase an accurate electronic scale, or to afford MCT oils.[53]
Like most diets, the ketogenic diet is not a one-size-fits-all answer to all of our health and weight hopes and dreams. It might be enjoyable for some people, especially in the short term, but that doesn't mean it will be a fit for everyone. The experts we talked to for this post agreed that although it may lead to short term (water) weight loss, it might not be optimal as a sustainable weight loss solution. St. Pierre explains the way he sums it up for his clients: “I let them know that there isn't a universal approach that works for everyone, and that restrictive diets like keto can be hard for folks to stick to long-term.”
Those issues can be part of what's known as the “keto flu,” Warren says. Other side effects of the keto diet, all of which are tied to carb withdrawal, can include lightheadedness, nausea, mental fog, cramps, and headaches, in addition to tiredness. Luckily, the keto flu doesn't usually last more than a week—which is coincidentally about when people start to see the number on the scale go down, says Warren.
This doesn’t mean that you can never have some of your favorite foods again.  Once you get past the adaptation phase and you have tested that you are in Ketosis, you can start experimenting with Keto versions of the foods you don't want to give up. Here are a few simple Keto recipes to start with. If you're looking for ready-to-eat Keto-friendly options, check out Country Archer Meat Sticks, Cuvee Coffee and FBOMB nut butters.
One of the most common side effects of starting the ketogenic diet is the “keto flu.” This term describes the often unpleasant, fatigue-inducing symptoms that occur as the body adjusts from a high-carbohydrate to a low-carbohydrate diet. During the keto flu, the body’s stored glucose begins depleting, and the body starts adapting to producing and utilizing ketones as energy. (2)
The gist of the eating plan? Taking in so few carbs sends your body into ketosis—a state of burning fat for energy, instead of carbohydrates or sugars, explains Beth Warren, RDN, founder of Beth Warren Nutrition and author of Secrets of a Kosher Girl: A 21-Day Nourishing Plan to Lose Weight and Feel Great (Even If You're Not Jewish). In order to stay in ketosis, you only consume 5% to 10% of your calories from carbohydrates—which for most followers is fewer than 20 grams total per day—and instead eat moderate amounts of protein and high amounts of fat.
Before we dive further into weight loss, a note: Weight loss isn't for everybody, and neither is following a specific, restrictive eating plan. If your goal is to lose weight, that's fine, but your health matters more than a number on a scale (and if you have a history of disordered eating, you should discuss any plans to change your diet with a doctor first). In addition, successful long-term weight loss is the product of many factors: Your physical activity, how much sleep you get, stress management, and other factors like medical issues and hormones all play an important role. What you eat is just one part of the weight loss puzzle.
While there have not been large studies that show the relationship between the ketogenic diet and cancer, we will be publishing a case study about that topic. The author failed to comment that pediatric patients with epilepsy are on the diet for usually about 2 years with no harmful effects. Before the false studies about heart disease and fat, the low carb diet was a respected way to lose weight. Studies into our metabolism show we can use both fat and carbohydrate as fuel. So stepping away from our high carb diet- I am sorry to say that we eat more carbs since the 70s with most of it processed and we now use high fructose corn syrup to sweeten products and we have a wide spread childhood obesity problem. If cholesterol is a concern try plant sterols and stenals to block cholesterol from the receptors in the body. So much more can be said about a keto diet than this article states

Because it lacks carbohydrates, a ketogenic diet is rich in proteins and fats. It typically includes plenty of meats, eggs, processed meats, sausages, cheeses, fish, nuts, butter, oils, seeds, and fibrous vegetables. Because it is so restrictive, it is really hard to follow over the long run. Carbohydrates normally account for at least 50% of the typical American diet. One of the main criticisms of this diet is that many people tend to eat too much protein and poor-quality fats from processed foods, with very few fruits and vegetables. Patients with kidney disease need to be cautious because this diet could worsen their condition. Additionally, some patients may feel a little tired in the beginning, while some may have bad breath, nausea, vomiting, constipation, and sleep problems.


Because the main tenet of the keto diet is counting and cutting carbs — a commonly used way to control blood sugar — this eating approach has become increasingly popular among people with type 2 diabetes who are looking to lower their A1C, which is the two- to three-month average measurement of blood sugar levels. Indeed, research suggests this diet may lead to fast weight loss and potentially lower blood sugar for people with the disease. (13)
This is a well-known phenomenon with nearly every type of diet: If you relax the rules even a little bit, you suddenly find yourself overeating. Making entire food groups—such as grains, sugar, and other carbohydrates—off-limits helps make them even more attractive, Macri says. This type of reaction goes beyond a psychological reaction—it can also be physical, she says. “Serotonin is one of the feel-good brain chemicals, and when serotonin decreases, such as it does when you’re on a strict low-carb diet, the brain is on high alert for any kind of reward,” she explains. Let some sugar or bread into your diet, and you could be overcome with a desire for more, Macri warns. “This makes it much more likely that you’ll overeat or even binge on those foods.” 
Josh Axe, a doctor of natural medicine and clinical nutritionist, estimates that about 25% of people who try a ketogenic diet experience these symptoms, with fatigue being the most common. “That happens because your body runs out of sugar to burn for energy, and it has to start using fat,” he says. “That transition alone is enough to make your body feel tired for a few days.”

I have great respect for Harvard Medical School. I notice that they support their readers posting comments and I am most appreciative of the article and all the many thoughtful comments by the readers. The readers seem to have the most expertise here and I hope that the doctor who wrote the article will think long and hard about the comments by readers. After 35 years of clinical practice in mental health, I notice that all issues of emotion involve medical issues, nutrition, and the gut bacteria. I would say that these issues and all of the executive brain functions seem to improve with ketogenic principles. For those that apply it in a flexible and smart manner, it appears to improve every area of their lives. I strongly encourage the author of the article to take one class via The Institute for Functional Medicine. If he is open to more learning he can take more classes and get certified. I’m sure a fine doctor, he will be an even better doctor and personally healthier, if he gets more training. Are we all open to new learning(especially us healthcare providers)?
There are numerous benefits that come with being on keto: from weight loss and increased energy levels to therapeutic medical applications. Most anyone can safely benefit from eating a low-carb, high-fat diet. Below, you’ll find a short list of the benefits you can receive from a ketogenic diet. For a more comprehensive list, you can also read our in-depth article here >

Ready to head out the door and start buying groceries? Slow down there, chief. Go through the pantry, fridge, freezer, and secret stashes under the bed, and get rid of foods with any significant carb content. In the first few days, you could end up craving them—badly. This means fruit, too. Even carrots and onions are too high-glycemic to work with keto, Wittrock says.


A study with an intent-to-treat prospective design was published in 1998 by a team from the Johns Hopkins Hospital[19] and followed-up by a report published in 2001.[20] As with most studies of the ketogenic diet, there was no control group (patients who did not receive the treatment). The study enrolled 150 children. After three months, 83% of them were still on the diet, 26% had experienced a good reduction in seizures, 31% had had an excellent reduction and 3% were seizure-free.[Note 7] At twelve months, 55% were still on the diet, 23% had a good response, 20% had an excellent response and 7% were seizure-free. Those who had discontinued the diet by this stage did so because it was ineffective, too restrictive or due to illness, and most of those who remained were benefiting from it. The percentage of those still on the diet at two, three and four years was 39%, 20% and 12% respectively. During this period the most common reason for discontinuing the diet was because the children had become seizure-free or significantly better. At four years, 16% of the original 150 children had a good reduction in seizure frequency, 14% had an excellent reduction and 13% were seizure-free, though these figures include many who were no longer on the diet. Those remaining on the diet after this duration were typically not seizure-free but had had an excellent response.[20][21]


Symptoms of the keto flu include headache, fatigue, dizziness, sleep problems, heart palpitations, cramps, and diarrhea. These side effects usually lessen and eventually resolve in about two weeks. (2) But to lessen the effects of any discomfort, simply consider slowly transitioning onto a ketogenic diet rather than rushing to change your eating habits. By slowly lowering your carbohydrate intake, while gradually increasing your intake of dietary fat over time, you can transition with less of a negative impact and potentially prevent the keto flu.

Welcome to the Keto Fit Diet. We have been in the weight loss industry for over 10 years now and have gone through every possible thread of research combined with clinical studies and our background in the healthcare industry in order to create the most successful weight loss method available. We have all struggled with getting rid of those unwanted pounds, using whatever unsuccessful means we could find. We have all tried the “miracle in a bottle” supplements, magic tricks and ridiculous diets to achieve our health and weight goals only to come up short or lose motivation before we ever see any real results. Well after 10 years of research, trial, error, and experience we have finally found the perfect, easy to use, solution to achieving our health and weight loss goals; the Keto Diet.
While it may be new to you, the keto diet has actually been around since the 1920’s, when the Mayo Clinic reported its effectiveness for helping epilepsy (that is still the case). Since then, there’s strong evidence that the keto diet helps with weight loss as well as type 2 diabetes, prediabetes, and metabolic syndrome, says Jeff Volek, Ph.D., RD, professor in the department of Human Sciences at The Ohio State University in Columbus, Ohio and co-author of The Art and Science of Low Carbohydrate Living.
Take a multivitamin. “Because you are removing grains, the majority of fruit, some vegetables, and a significant amount of dairy from your menu, a multivitamin is good insurance against any micronutrient deficiencies,” says Jadin. Depending on what your individual overall diet looks like, Jadin says you might also need to add a calcium, vitamin D, and potassium supplement.

This means that to achieve ketosis, you have to limit your carb intake to less than 50 grams per day (most people should reach ketosis within a week of following the diet). To put this in perspective, the low-carb diet you’re most familiar with—the Atkins Diet—recommends about 130 grams of carbs per day. Also for reference, one bagel has about 55 grams of carbs.


So people saying that – despite the lack of scientific support – likely have a financial reason to say it. Some of these products are sold under something like a multi-level marketing arrangement, so sales people are entirely paid based on commission. For example, the company Prüvit sells drinkable ketones, called KETO//OS with a multi-level marketing structure.
