The ketogenic diet is based on the principle that by diminishing the body of carbs, which are its main source of power, you can force the body to burn fat for gas, thus taking full advantage of weight loss. When you consume foods that contain carbs, the body transforms those carbohydrates into glucose, or blood glucose, which it after that makes use of for power. https://www.everydayhealth.com/diet-nutrition/ketogenic-diet/
