This diet is based on the theory that glutonous people consume heavy amounts of carbohydrates. Our bodies breakdown both fat and carbohydrates for energy, but carbs are used initially. By drastically reducing carbs and eating more protein and fat, our bodies naturally lose weight by burning stored body fat more effectively. By restricting carbohydrates extravagantly the body goes into the process of Ketosis, meaning that the body fat is burning to provide fuel for energy. In this phase the person will get energy for ketones, which are little carbon fragmentations created by the burning of fat stores. Ultimatley, your body changes from a carbohydrate-burning engine into a fat-burning engine. So instead of relying on the carbohydrate-rich items you might typically consume for energy, and leaving your fat stores just where they were before (alas, the hips, belly, and thunder thighs are popular fat-gathering spots), your fat stores become a primary energy source. The result is weight loss!!
