Keto diets are defined by a low carbohydrate (typically under 50 grams/day) and high fat intake, leading to an elevation of free fatty acids and ketone bodies in the blood. The first ketogenic diets in the medical literature are noted in publications in the 1920s, although wider popularity and increased research was not seen in medical literature until the 1960s. Variations of the diets have remained popular for the past 20-30 years, with proponents claiming that the diets boost weight loss and energy while offering protection from certain metabolic diseases. A ketogenic diet and fasting affect the body similarly. Both deplete the body’s glucose reserves, so the body starts turning fatty acids into ketones.
