In this paper we argue that compulsive overeating has compelling similarities to conventional drug addiction. Our case is based on their comparable clinical features, the biological mechanisms they have in common, and on evidence that the two disorders have a shared diathesis. In making the argument for overeating as an addictive behaviour, it is clearly not appropriate to include all cases of excessive food consumption in this taxon. Nor are we claiming that obesity and addiction are one and the same. However, it is proposed that Binge Eating Disorder (BED) is a phenotype particularly well-suited to such a conceptualization, and that sound clinical and scientific evidence exists to support this viewpoint. We have provided some recommendations for treatment modifications that recognize the similarities between treating drug dependence and compulsive overeating.
