Reward circuit function in high BMI individuals with compulsive overeating: similarities with addiction.

Abstract

The rising rate of overweight and obese individuals among developing countries despite focused efforts on prevention and treatment underscores not only the need to better define the physiological factors that contribute to weight problems, but also the need to elucidate the neurobiological mechanisms of the self-regulatory failure over eating that leads to weight problems. Emergent findings suggest an overlapping model of addiction and compulsive overeating.
