This eating plan certainly contradicts most people’s understanding of a healthy, balanced diet which typically promotes the consumption of protein, fat and carbohydrates. From an evolutionary perspective, ketosis is a normal adaptive response which enabled humans to withstand periods of famine throughout history. Today, this natural physiological mechanism has been exploited by a number of low-carb diet regimes. 

Note that the term “reversal” in this context simply means that the disease gets better, improving glucose control and reducing the need for medications. In the best case, it can be so much improved that blood glucose returns to normal without medication, long term. In this context, reversal means the opposite of the disease progressing or getting worse.
A low-fat diet may be preferable for some individuals while other individuals may do better on a low carbohydrate diet. The fact that I may recommend a Paleo or an Atkins type diet for some people, does not mean that I am against whole grain or potatoes. Although  I recommend everybody to avoid simple refined sugars and junk food, I think complex carbohydrates, starches, and not least fiber can be a part of a healthy diet for many people.
When you eat less than 50 grams of carbs a day, your body eventually runs out of fuel (blood sugar) it can use quickly. This typically takes 3 to 4 days. Then you’ll start to break down protein and fat for energy, which can make you lose weight. This is called ketosis. It's important to note that the ketogenic diet is a short term diet that's focussed on weight loss rather than the pursuit of health benefits. 

Hi Michele, Calories don’t directly correlate with rate of weight loss. If you are looking to lose weight, then I suggest looking at the amount of fat you are consuming in a day and possibly adjust that. With keto, fat is used as a lever. You don’t have to eat the full amount of fat listed in your macros if you don’t need it. Eat until you are no longer hungry.
Insulin is a hormone that lets your body use or store sugar as fuel. Ketogenic diets make you burn through this fuel quickly, so you don’t need to store it. This means your body needs -- and makes -- less insulin. Those lower levels may help protect you against some kinds of cancer or even slow the growth of cancer cells. More research is needed on this, though.
When you’re following a traditional ketogenic diet, you consume around 75 percent of your daily calories from healthy fats, 5 percent from carbohydrates and approximately 20 percent from protein. In general, ketogenic diets typically limit daily net carb intake to just 20–30 grams, which is calculated by subtracting the number of grams of fiber from the total number of carbs.
Thanks for the reply. What’s most confusing is that keto introduced many low-carb but high fat, and therefore, caloric foods. So for instance, before keto, I drank black coffee. On keto I switch to full fat cream and I really like it so I’m still drinking coffee with full fat cream but that means I’m consuming about 5 times the amount of calories I would with my coffee. In ketosis it doesn’t matter because that fat is used up directly as fuel for the day, but if I’m not in ketosis should I switch back to black and start counting calories again?

My husband and I started keto Jan 1st 2019. By mid Feb. He lost 11 lbs and I lost 8 lbs. Even though we were faithfully not eating many carbs I got out of ketosis and could not seem to lose another pound. Then we got sick with bad cold and stomach issues. We went off on the 14th of February. And I’ve already gained about 6 lbs. My husband gained about 4 lbs. Plus we got sick of eating the same thing over and over. He is a diabetic and while on it his numbers were so much better. HELP WHAT DID WE DO WRONG?


Ketogenic diets were originally developed to treat epilepsy in children as it appears to reduce the frequency of seizures. It should be noted that using the diet in this context should not be attempted without the supervision of a specialised doctor. From these medical origins, the diet was picked up by the mainstream media and marketed as a weight loss regime – it is in this context that we will be discussing the diet for the purpose of this article.
I too love your site. Your keto recipes are the best! ….I’ve been on Keto for over a year now and have lost 100 pounds. I still have another 100 to go, but I’m still losing……. Another thing to look at is the influence that the sugar industry has had on today’s high carb diets. When food went low-fat, they added extra sugar. The sugar industry has a lot of money and lobbyist tied up in the way Americans eat. They really don’t want us to know that doing without sugar and eating more fat is the healthy way to go.

Hi Sandy, I’m not a doctor so cannot give medical advice, but do have years of research and experience in this lifestyle. Kidney failure can happen due to excessive protein intake, which was more prevalent on older versions of the Atkins diet. This is a common misconception with low carb and keto diets – that they have to mean high protein – and they shouldn’t be. If you keep your protein in check, it shouldn’t be an issue. But, I would definitely consult with your doctor since you have had issues with this.
