The keto diet, also known as the low-carb high-fat diet (LCHF), consists of reducing the number of carbs while increasing the fat.
In a regular diet, about 55% of the energy comes from carbs, 35% from protein, and 10% from fat intake.
In Keto, it is quite different. Most of the energy intake comes from fat while carbs only make up about 10%.
This vast reduction of carbs consumed is putting the body in a state called Ketosis.
