We have been trained, as Americans, to believe that our bellies should be full all the time. Any twinge of hunger is a bad thing and we must immediately put something in our mouth to satiate the hunger.

And it’s this “normal” American eating schedule, involving multiple meals and snacks, that is causing so many of the physical and health issues Americans are facing.
