Abstract

The increasing worldwide prevalence of obesity is partially related to the ready availability of highly palatable foods which increases the incidence of hedonic, non-homeostatic feeding. The "food addiction" hypothesis postulates that exposure to these foods alters the brain's reward circuitry, driving an addiction-like behavioural phenotype of compulsive overeating. This review highlights recent evidence that examines changes in the mesolimbic dopaminergic circuit, the primary component of the reward system, associated with exposure to highly palatable foods and obesity. The majority of obesity studies in animals have not measured addictive-like behaviours, but reports of such behaviours have been restricted to experiments using models of binge eating. Where examined, the prevalence of addiction-like behaviour in overweight and obese subjects indicates that 10-25% of the population meets the Yale Food Addiction Score criteria. There is considerable overlap in the behaviours ascribed to food addiction and binge eating disorder, and food addiction scores correlate highly with measures of binge eating. We feel that more research is required in humans to determine whether food addiction is both behaviourally and neurobiologically distinct from binge eating disorder. While the reward circuitry is clearly affected by both highly palatable foods and diet-induced obesity in a similar manner to short and long exposure to drugs of abuse, the challenge for the future is to show that these neurobiological changes are associated with addiction-like behaviour.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
