Almost all people who want to lose weight are only annoyed, again and again listening to the advice "eat less, move more." But how to understand which piece of food or a sip of liquid is superfluous, which training will become decisive? Gary Taubs, a journalist and best-selling author on nutrition, was a "chubby" himself all his life, but after studying the mechanisms of overeating and various diets he was able to achieve a healthy and optimal weight. In this book, he shares the possibility of not only and not so much losing weight as improving. After all, the keto diet, which he is talking about, will allow you to lose extra pounds, tidy up your health indicators and at the same time be saturated enough not to be drawn to the forbidden fetus.
