Behaviorial Neuroscientists point of view: the DSM-5 [118] does not recognize FA in itself, but it identifies different forms of substance-related and addictive disorders (including gambling) that can be used as a reference framework for our discussion. In this context, if we accept the existence of FA, then the neurobiological characteristics of substance-related and addictive disorders should reveal common patterns between food and drug abuse. The point is that the FA construct must be supported by precise definitions, as well as dedicated neurobiological and neuroimaging studies. These definitions must be supported by concrete data and not only by shortcuts based on analogies with obesity or food abuse. Even though we must assume that substance addiction always starts with substance use, not all obese and/or bingeing ED-subtype patients have FA, and not all “food addicts” are obese. All these data support the existence of a specific FA brain phenotype that can be detected in normal-weight, overweight, or obese individuals and that is characterized by anomalies in the reward and inhibitory control processes, with likely corollary consequences in the limbic/emotional and cognitive/attentional spheres (Figure 2). Even though a recent meta-analysis of fMRI studies defends an addiction model of obesity, characterized by reduced cognitive control and interoceptive brain responses [141], this vision is probably restricted to part of the obesity spectrum and cannot be generalized to all forms of obesity
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.
