Because it is related to more than diet. There is a ton of literature on all of the different factors that induce insulin resistance (assuming you are talking about type 2). Diet, lack of exercise, genes, pollution, stress, chronic inflammation, the list goes on. And there isn't a type to look like. The idea that only obese people have type 2 is ignorant at best. Consider yourself lucky you have type 2, you can control it very easily if you choose to do so. I would gladly swap my son't type 1 for type 2 any day of the week.
