Insulin has another unique job, it also prevents the stored fat from leaving the fat cell. In essence, some experts believe that eating more carbohydrates stimulates your body to store more fat. Think about eating a baked potato. You thought the extra sour cream and butter was making you fat. It may actually be the potato, due to the insulin response.
People think that cholesterol is bad, but it is critically important to human health.
If our diet does not provide enough cholesterol, our body will produce it. From the discussion of insulin above, high-carbohydrate diets may backfire, by producing an imbalance of insulin in your bloodstream. Additionally, and no less alarming, those on high carbohydrate diets may also lose muscle. Nobody should want to lose muscle. A given mass of muscle burns more calories than the same mass of stored fat.
