The ketogenic diet deprives the body of carbohydrates for fuel. Instead, the body uses ketone bodies, a type of fuel that the liver produces from stored fat. Keto diet followers must eat fat at each meal. In a daily 2,000-calorie diet, that might look like 165 grams of fat, 40 grams of carbs, and 75 grams of protein. Ditching carbs means limiting fruits and vegetables, which raises the risk for nutrient deficiencies. The keto diet also increases the risk for kidney, liver, mood, and thinking problems.
