Obesity is a disease of fat storage and reduced fat utilsation. Understanding this concept can lead you to successful weight loss. How many people try and lose weight and fail? Of course there are many reasons for this but one is that insulin locks up body fat. When your energy is derived from carbohydrates (sugar) you are using insulin produced by your pancreas. Over time insulin levels rise higher and higher because your body becomes resistant to insulin, this is called insulin resistance. High insulin levels stop the body from using stored fat. To break this cycle you have to significantly reduce dietary carbohydrate so that your body can burn fat. If this does not happen obesity may lead to diabetes and the failure of insulin production.
