Compulsive eating, which is also often called compulsive overeating or food addiction again refers to this pattern of behaviour where someone will eat past the level of comfortably full in a way that feels out of their control. And just like with binge eating, compulsive eating is often followed by feelings of regret and shame.
These compulsions to eat when not hungry or past full usually follow the same threads as binge eating; perhaps due to being on a diet or restricting food in other ways, the desire to avoid uncomfortable emotions, an underlying feeling of not being “enough” or a combination of all of these.
Compulsive eating however, although it’s a form of disordered eating, isn’t “officially” recognised as an eating disorder, in the way that binge eating disorder, bulimia and anorexia are.
