New brain research shows that overeaters may have a more sensitive and over-reactive brain whenever they see, smell, taste, or even think about food. The reward system in the limbic areas respond more strongly, and tell us that we must eat now, and as much as possible.
In the past, before food was plentiful and cheap, this primitive response was a survival mechanism. Today, it can be a liability, for each time we see a fast-food restaurant, or a picture of a person enjoying a bite to eat on a commercial, our brain sends out a warning: Eat now, for tomorrow I may starve!
Thus, for some of us, overeating is not so much a lack of willpower, or low self-esteem, but a natural biological and neurological process that is fundamentally out of touch with the fact that food is readily available. However, we can train our brains, through mindful eating and conscious commitment to override our propensity to overeat.
