Food addiction is an emerging area of both clinical and research interest. The current review discussed several definitional and conceptual categorisations that have been put forth to quantify food addiction. However, the YFAS 2·0 concept predominates the literature. Similarly, evidence shows some similarities of food addiction with established eating disorders, particularly BED. Thus, the current review supports two main areas of contention that warrant much more research; considering food addiction as a substance-related addiction or a behavioural-related addiction and if food addiction is distinct from established eating disorders. Further research is needed to continue to delineate and clarify controversies about similarities and differences in food addiction with other concepts and established disorders.
