When carbs are digested they’re broken down into glucose which is used by the body as energy. When glucose enters the blood stream the pancreas reacts by releasing insulin. The amount of insulin released by the body is comparable to the amount of glucose in the blood stream. When one is high so is the other and vice versa. The idea is to keep your glucose and insulin levels as low as possible because insulin is a fat storage hormone. Do this by eating complex carbs.
