Re: serum insulin level "high"???
I believe that what this indicates is that you are insulin resistant. Your body does not deal with the insulin properly so it is forced to over produce it. With normal blood sugars (I'm assuming this because you don't mention it) you do not currently have diabetes, but unfortunately you are probably on the road there. Ways to combat IR are to get more active (walk, run, bike, etc) and cut back on "white" foods. That is foods that are high in carbohydrate, low in fiber, and are easily broken down and absorbed. Things like rice, potato, breads, pasta, etc. Eating more fiber will help as will reducing any excess body fat if you have any. Has your doctor discussed these results with you? A trip to a dietitian or nutritionist might be in order.
