Obesity is undoubtedly one of the leading health problems today. According to some authors, the main cause of obesity is a high intake of carbohydrates. This hypothesis has contributed to the creation of a large number of diets with limited carbohydrate intake, including the keto diet. Considering the great popularity of this diet and the large num...
