The Keto Diet suggests that you reduce the percentage of carbohydrates and make your diet heavier in protein and fats. When you decide to go on a Keto Diet, your meals generally consist of 65% fat, 30% protein, and 5% carbohydrate. If the body gets less than 20 grams of carbohydrate each day, it goes into ketosis, a metabolic process that burns stored fat to produce ketone bodies that supply the energy required to run your body.
