I dont think thats the central message of the film at all. the problem with human digestive system is that it evolved for very different set of conditions & has very limited 'floating' capacity for carbs. so when you eat highly processed food with short chain carbs what you get is sudden overload in carrying capacity of blood stream. body responds by storing it away as fat. OTOH when you are short on energy body produces hunger signals before tapping into fat reserves so eat again & cycle repeats. the message IMO is about composition of what you eat (centered around sugar).
