Successful dieters increase the size of their anterior mid-cingulate cortex, while those who fail to reach a diet goal experience a shrinking of this brain area.

“indeed successful dieters show elevated spontaneous and what's called evoked levels of activity in the anterior mid singulate cortex so spontaneous again just at rest they have higher levels of activity in the anterior mid singulate cortex and for those that are presented with food and they have to resist that food and they have to resist the smell of that food and the potential taste of that food the activity of the anterior mid singulate cortex goes up even further especially in those individuals who can resist that is who can engage willpower to not eat the delicious food item”
