Do you look at someone who carries extra weight and think they might have diabetes, or maybe other metabolic health problems, and yet you never think that about someone who is of normal weight? Many medical providers fall into this trap, and it's a dangerous way of thinking. It means those of normal weight often fail to get the screening tests that would determine if they are one of the 30% of normal weight folks with insulin resistance! They are at high risk of developing diabetes, and yet they don't know about it until the deal is done.
