The ketogenic diet, popularly known as the keto diet, is a low-carb, high-fat diet regime. The reduced carb intake puts the body in a metabolic state known as ketosis, and this is one of the best diets for reducing blood sugar levels. It is also recommended for weight loss. A keto diet would limit your daily carb intake to 20 to 50 grams, but there are many nutritious foods that can be included in the daily food list to compensate for the reduced carb content through fats and other nutrients.
