Why follow the keto diet?

By drastically reducing carbohydrate intake and increasing fat intake, the body is forced to use fat for energy, rather than storing it. The body thus “burns” more fat, via the liver, converting fats into ketone bodies that can serve as energy substrates for cells. Prolonged use of ketone bodies as the main source of energy leads to a state called ketosis, during which the body is primarily carbohydrated with fats that it also derives from adipose tissue. The resulting lipolysis aids rapid and permanent weight loss.
