Our daily stresses and mental fallacies make fighting obesity an uphill battle.
We can think of our brain as being engaged in a constant ebb and flow between deliberate and automatic processing. Sometimes it is more of a fight between two mismatched warriors, like David and Goliath. David represents the small, nimble, and smart cognitive force that has to face a massive, primitive, noncognitive giant that is in charge most of the time. Goliath is unflagging and never sleeps. Sometimes David can win, but it is nearly impossible for him to win all the time. David can be distracted, he can be worn down, and he needs to sleep. This is not a single battle but an eternal struggle.
Although distractions can lead to overeating, the limits of our memory also contribute to eating too much. When amnesiacs with no short-term memories were offered meals in quick succession, even just one minute apart, they kept on eating and consumed full plates each time. Afterward, they reported no change in their feelings of hunger because they didn’t remember that they had already eaten.
