This kind of behavior shows that food addiction is not only a self control problem, but that it goes deeper than that, it is the body controlling a person to the point where the individual has no say on what goes into their bodies despite all the consequences that can come from overeating.
To show this, a study done by Sara Parylak and her peers in the physiology and behavior journal reveals that animal models given free access to food became more emotionally withdrawn after the food was taken away from them due to the anxiogenic-like stimuli pestering them for more food. The person’s behavior then begins to shift when the need for more food is not met, in that when the urge is met, binge eating, obesity and bulimia can result as a consequence. At first, the food addiction comes in the form of cravings, so a person is naturally caught unaware when suddenly they find that they cannot cope without the craving. The term binge eating means eating an unhealthy amount of food while feeling that one's sense of control has been lost. "Food addiction" refers to compulsive overeaters who engage in frequent episodes of uncontrolled eating ( binge eating).

Because this addictive behavior is not biological, one cannot develop a trait that codes for an eating disorder, so professionals address this by providing behavior therapy and by asking a series of questions called the YFAS questionnaire, a diagnostic criteria of substance dependence. Psychological dependence has also been observed with the occurrence of withdrawal symptoms when consumption of these foods stops by replacement with foods low in sugar and fat.
