On the surface, food addiction makes sense. America remains in the throes of an obesity crisis, and heart disease—a condition heavily influenced by poor dietary choices—still kills more Americans than any other cause. Against that backdrop, the addictive nature of our favorite foods seems to explain our ongoing willingness to overindulge despite the often-fatal consequences.

But the food addiction narrative begins to unravel the more experts scrutinize it, raising questions proponents of the hypothesis don’t have good answers for. For example, only a minority of obese people fit the definition for food addiction while a larger share of patients diagnosed with anorexia do. This paradox badly undermines food addiction and goes to a broader point: the diagnostic criteria are not distinct from existing disorders. Indeed, large-scale studies show that food addiction symptoms almost perfectly overlap with binge-eating disorder and normal overeating driven by stress or restriction.

Once those factors are controlled for, an independent “food addiction” syndrome disappears. “Collectively, the present findings support the view that [food addiction] reflects a cluster of preexisting psychological constructs—such as craving, guilt, and disordered eating attitudes—rather than a clearly delineated disorder,” the authors of a July 2025 review concluded.

Perhaps more importantly, no unique addictive agent has been identified. Decades of searching for a “food drug” (sugar, fat, palatability) have failed. While some mental health experts insist there is an “emerging consensus” about the validity of food addiction, they can’t seem to settle on exactly what quality makes a certain dietary choice addictive. This seriously undercuts any attempt to analogize food addiction to a well-established substance use disorder like alcoholism.

In short, “food addiction” is a metaphor stretched into a diagnosis. It pathologizes common human struggles and distracts from evidence-based drivers of overeating: sleep deprivation, emotional distress, and the modern food environment’s relentless cue exposure. The science has moved on; the label should too.
