The ketogenic diet is a high-fat, adequate-protein, low-carbohydrate diet. The goal of the diet is to get your body into ketosis—a metabolic state which prioritizes fat as your energy source.
Ketosis is a natural process that the body initiates to help us survive when food intake is low. It also occurs when your body has run out of its glycogen (sugar) stores, so it needs to find another source of fuel. When you are in ketosis, your liver begins to produce ketones by breaking down fat. These ketones then become your body’s main fuel source.
The end goal of a properly maintained keto diet is to force your body into ketosis not through starvation, but through the absence of carbohydrates. Optimal ketone levels offer many health, weight loss, and physical and mental benefits.
