There is a theory (and I want to stress that it's theory, not fact) that many processed foods may not trigger our indicators of satiety. Some foods trigger satiety better than others, and we have pretty good evidence that a lot of sugars don't cause satiety.

On the other hand, foods like rice, potatoes, etc do.
