You're exactly right. As long as nutritionists and doctors keep pushing people to eat grains at such massive rates, nothing is going to change as far as obesity is concerned. They are simply blinding themselves to the fact that all starches raise blood sugar and therefore insulin levels and therefore body fat storage. They KNOW this.

They know that no matter what minisucle amounts of fiber a whole grain or baked potato might have in it, and despite how much they've been taught in school about the need for whole grains, they know that such massive quantities of carbs are going to go to fat storage. They know the math, they know how much blood sugar we need at any given time, they know how much blood sugar the brain needs to function, and they know how much blood sugar a single potato or slice of whole grain bread, or bowl of oatmeal will convert to.

There's just some kind of blindness, some kind of disconnect in their insulin flooded brains, as if they think that our pancreas lives in some kind of la-la land and only provides insulin to convert the excess starch to fat if it happens to be a refined carb, but leaves the whole grain starches alone.
