Hyperinsulinemia?: You may have insulin resistance and hyperinsulinemia. Insulin is the hormone that drives sugar into your cells where it is stored as fat. I suggest a low-carb diet, and the drug Metformin (1500-2000 mg per day). Metformin restores insulin receptor sensitivity, and reduces the production of glucose by your liver (which triggers more insulin). Exercise (15 min walk/day) will also help.
