“If you’re going to do keto, there’s a better and a worse way to do it,” says Yawitz. “Loading your plate with meats, and especially processed meats, may increase your risk for kidney stones and gout,” which is a painful type of arthritis. “High intake of animal proteins makes your urine more acidic and increases calcium and uric acid levels. This combination makes you more susceptible to kidney stones, while high uric acid can increase your risk for gout,” adds Yawitz.
But this state of metabolic derangement is not actually possible in a person who can produce insulin, even in small amounts.  The reason is that a feedback loop prevents the ketone level from getting high enough to cause the change in pH that leads to the cascade of bad problems.  A person who is said to be “keto-adapted,” or in a state of nutritional ketosis, generally has beta-hydroxybutyrate levels between about 0.5 and 3.0 mM.  This is far less than the levels required to cause harm through acid-base abnormalities.
Luiza Petre, MD, a board-certified cardiologist and weight management specialist in New York City, suggests focusing on eating more low-carb, fiber-rich foods that can help beat this bowel issue. “Try fibrous vegetables, such as broccoli, asparagus, and cabbage, consume more fat like MCT oil, coconut oil, or ghee, and, as always, drink plenty of water,” she says.

Hey Edwin, I personally have been following one for years with no issues. I cycle out once every 1-2 weeks with a higher carb day using low glycemic carb sources like root vegetables. One of the keys for me has been keeping it simple and finding ways to use staple ingredients (such as avocados and coconut products) to make a variety of recipes.Check out this article for some examples https://drjockers.com/ketogenic-avocado-recipes/
Dehydration. With fewer water-binding carbohydrates in the diet, the body is less able to hold onto fluids, which can lead to dehydration. Eating more salt can help offset this, but it can also raise blood pressure, creating a whole new set of issues. If you plan to follow a keto diet, hydration is key. To know how many ounces of fluid you need each day, Yancy recommends dividing your body weight in half. Then think of the resulting number as your daily fluid goal in ounces. So if you weigh 200 pounds, strive for 100 ounces of water a day.

For people with Type 1 Diabetes, you probably have heard of their diabetic emergency, diabetic ketoacidosis, also referred to as DKA. This can be life threatening condition for people with Type 1 diabetes and Certified Diabetes Educators spend many hours teaching preventive care for DKA. This condition should not be confused with nutritional ketosis, the fat burning state reached when following the Ketogenic diet. The two conditions are quite different.
I suggest you or other readers who are not familiar with Dr Wahl's work and research into autoimmune disease and brain biology get a copy of 'The Wahl's Protocol'. Medicine and nutrition are ever-changing sciences and sadly we can't rely on our standard medical practioners (or registered dieticians) to share important research we should all be able to access.
With fats being my main source of calories, my body and energy levels have never been better. When I educated myself on it and understood the science behind it, it was clear to see why my joints started feeling better, and ailments started to go away. I now have more “oil” lubricating my cells so they’re more receptive/flexible/malleable to the nutrients in my foods. People can loose weight very fast, but honestly the first 10lbs or so is a lot of water weight so that’s really nothing to write home about.
As someone who is prediabetic, Keto has been a godsend! I thought I was just a glutton, but now I’m certain I am actually insulin resistant. I am on Keto and can manage half a cup of blackberries without coming out of ketosis, but almost any other carb/sugar and I become a mindless food consuming zombie. I literally feel like I have zero control over my ability to stop eating. Also before trying Keto, if I was not able to eat constantly throughout the day I became grumpy and tired. Like none tired where it felt like I had lead running through my veins. On Keto, I can go a good 5-7 hours without eating and I don’t feel off at all. I am hoping to lose weight, but mostly I do not want to become diabetic and my problem is that I am insulin resistant. I do plan eventually to eat more black beans, vegetables and fruits again. Maybe a little chocolate on holidays and cake and ice cream on my

But wait, there’s one loophole. Have polycystic ovary syndrome (PCOS)? Then the keto diet may help regulate your periods. “Women with PCOS have high insulin levels, which cause sex hormone imbalances,” notes Yawitz. In a small study published in the journal Nutrition & Metabolism, subjects with PCOS following a ketogenic diet for six months noted improvements in their menstrual cycles — and a small number of women became pregnant, overcoming previous infertility obstacles. “This study was very small, so we can’t make recommendations for all women with PCOS based on its findings,” says Yawitz. “And really, any diet that leads to weight loss should help in PCOS.”


Having said that, there are also studies suggesting that long term carbohydrate restriction diets (aka. the keto diet) may result in fast short term weight loss but people gain it all back in the long term. An RCT put 63 individuals on a low-fat diet or a low carb diet, and the study found the low carb dieters lost more weight compared to the low fat group by month 3 and 6, but that the weight loss evened out by month 12. This was confirmed by a Meta-analysis which found that while low-carbers lost more weight than low-fat dieters but the differences disappeared by the one year mark.
Nutritionists frequently advise clients to reach for more healthy fats and protein to stay full throughout the day. With this in mind, it makes perfect sense that a ketogenic diet would be about as good as it gets for staying satiated. One study from the American Journal of Clinical Nutrition found this type of low-carb approach was more effective for weight loss and managing hunger than a similar high-protein diet with a greater percentage of carbohydrates. One 2013 study even suggested the eating plan may suppress hunger hormones more effectively than other weight-loss programs.

I must note here, that as a nutrition professional who has worked in pediatrics and seen children who must follow this diet, it is incredibly challenging for both the child and family. Most people who must follow this diet for therapeutic medical reasons have trouble actually reaching ketosis with diet alone, and need to drink poor-tasting formula drinks to keep their carb-to-fat ratio in tight control. Many of these individuals must follow this way of eating to survive or have any sort of quality of life.
Click here to join my newsletter and I’ll keep you posted when I get new articles up (FYI: as a heads up, I also write about entrepreneurship and web development. I started writing about fat metabolism and ketogenic dieting here at KetoSchool out of pure hobby interest, as there are relatively few resources out there that teach the underlying science).
Consider a 135-pound woman who has about 25% body fat and 100 lb of lean mass. If she follows a 2,000 calorie diet, she would be eating between 145 – 179 grams of fat, 50 grams of protein, and between 50 – 124 grams of carbohydrates (depending on her activity level). She would need to keep her carbohydrates under 50 grams a day in order to “keto-adapt” (for her body to adapt to using fat as the primary fuel).
In order to transition and remain in this state, aiming for about 30–50 net grams is typically the recommended amount of total carbs to start with. This is considered a more moderate or flexible approach but can be less overwhelming to begin with. Once you’re more accustomed to “eating keto,” you can choose to lower carbs even more if you’d like (perhaps only from time to time), down to about 20 grams of net carbs daily. This is considered the standard, “strict” amount that many keto dieters aim to adhere to for best results, but remember that everyone is a bit different.
Hello Dr. Jockers, in the past few months I have been working on cleaning up my diet. Eating gluten & dairy free as much as possible. I started taking exogenous ketones at the same time. I got a juicer for Christmas and about 3 weeks ago I added celery juice ( 1st thing in the AM) and a carrot, apple, turmeric juice in the afternoon. Some days I am fine and other days I have sudden diarrhea within an hour of drinking the celery juice. I’ve read so much about the benefits of drinking it but am wondering if the ketones are reacting to it adversely? Please let me know your thoughts on this.
This plan entails eating about 120 grams of protein per day (or four 4-ounce servings of meat, fish or poultry) and around 130 grams of fat per day. Carbs are still restricted to less than 10% of daily calories. But many people find this modified keto diet easier to follow, because it allows you to eat more protein and less fat than the standard keto diet. The caveat is that this approach may not result in ketosis, because like carbs, protein can be converted into glucose for fuel. But the high-protein keto diet will generally result in weight loss.
Lazy keto diet: Last but not least, the Lazy keto diet often gets confused with dirty keto … but they’re different, as the “lazy” refers to simply not carefully tracking the fat and protein macros (or calories, for that matter). Meanwhile, the one aspect that remains strict? Not eating over 20 net carb grams per day. Some people find this version less intimidating to start with or end with … but I will caution that your results will be less impressive.
My son started the Keto Diet (not perfectly) with the ok of his Dr and a Different Oral Chemo at the same time. Last Tuesday an MRI indicated no new growth or no new tumors. We don’t know if the new Chemo, Keto diet, lots of prays or what has stopped the tumors from growing.I found your site after looking for possible adverse reactions to Keto Diets, and appreciate your research. His platelets are low now and never have been low before. This is stopping the next Chemo treatment. I understand that being on Chemo for 12 months could have created the low platelets and now the possibility that the Keto Diet could also be causing low platelets is frustrating. They will do a new blood test Tuesday to see if the platelets have increased. Any suggestions about how if possible to increase the platelets on the Keto Diet would be helpful.
In another study on women, researchers confirmed that the ketogenic diet resulted in favorable changes in LDL particles consistent with lower cardiovascular disease risk. However, the total LDL cholesterol did not change. This is why it is important to test the levels of different LDL particles. Looking at the LDL number itself may be misleading, especially on the ketogenic diet.
Ketones are more beneficial to the brain than glucose is.  This is great news for patients with Type 1 Diabetes, because it will not affect the brain function when you are running low in glucose. Ketosis prevent raising blood glucose levels, since you are not introducing large amounts of carbs into your system. They help in stimulating the growth of healthy brain cells.
An extensive review published in 2013 looked at the research and evidence of ketogenic diets enhancing fertility (long story short, it looks promising). Studies also show that Polycystic Ovary Syndrome (PCOS) can be treated effectively with low-carb dieting, which reduces or eliminates symptoms such as infrequent or prolonged menstrual periods, acne, and obesity.
We are brazilian, living in Brazil. My daughter, Isabel, 21y. o., born in 1996, has syndrome of deficiency of Glut1. She was diagnosed around her first year of life. At that time her baby bottle, her begining diet meal, was 50ml water plus 50ml oil plus vitamin. Since then, which means, for 20 years, she is under this diet. For almost 18 years under 4:1 proportion. At this right moment 3:1. The only problem she had since started the diet were kidney stones in 2002. Nothing else. Grateful to the diet she doesn’t take any kind of medicine to avoid seizures. Her health is perfect, no colesterol at all. We are at your will for any issues related to her health.

Type 1 diabetics, for now, nearly always need some insulin. How much they need and how effective the exogenous insulin is at controlling their blood sugars largely depends on how well they followed a well-formulated low-carb or ketogenic diet. What it comes down to is that the diet allows you to deal with the easier task: covering your basal insulin needs. Off the diet, people are faced with the harder task: covering basal insulin needs + those arising from carby foods.
Our bodies are incredibly adaptive to what you put into it – when you overload it with fats and take away carbohydrates, it will begin to burn ketones as the primary energy source. Optimal ketone levels offer many health, weight loss, physical and mental performance benefits.1There are scientifically-backed studies that show the advantage of a low-carb, ketogenic diet over a low-fat diet. One meta-analysis of low-carbohydrate diets showed a large advantage in weight loss. The New England Journal of Medicine study resulted in almost double the weight loss in a long-term study on ketone inducing diets.
If you’re wondering why iron is at risk on a meat-based diet, hear me out. Many grain foods provide a considerable amount of iron, because wholegrains naturally contain iron in their inner layer called the ‘germ’. Another reason is that some grain products can have iron added to them during manufacturing. So, once you cut grains out, your iron status could suffer, which can lead to unpleasant symptoms like tiredness and lethargy. It can even compromise your immune system.
