The Ketogenic Diet is defined as a low-carbohydrate, moderate protein, and a high-fat diet. By eating more fat and fewer carbohydrates, your body uses more fat as fuel for energy, rather than carbohydrates.
When humans consume carbohydrates, the body does one of two things: it either burns the carbs for fuel or stores these carbs as fat in the body.
So when the body has fewer carbs and more fat, the body converts this fat into ketones and forces the body to be in the state of ketosis. Ketosis is a normal metabolic process wherein ketone bodies are produced, which are fatty acids that the body can use to produce energy.
When the body is under ketosis, the body burns more fat to use as energy, helping humans to lose unhealthy fat storage, and build more lean muscle mass.
The Ketogenic Diet then consists of high consumption of fat food, moderate portions of protein, and very little carbohydrates.
