“…The meta-analysis revealed that, according to the YFAS, the mean prevalence of the diagnosis of "food addiction" was almost 20%, being higher in patients suffering from BN than in cases of BED. In accordance with most of the aforementioned studies, "food addiction" was associated with higher tendency to binge eating, depressive symptoms, impulsivity, and emotional eating [48].…”

Eating disorders (ED) seem to share many characteristics with substance-related disorders (SRD). As very often the two conditions run together, it has been proposed that eating dysfunctions could be understood as behavioral forms of addiction. This has lead to the concept of "food addiction," a proposed new form of addiction. This chapter reviews recent research focusing on the relationship between ED and SRD. Three specific areas are addressed: (a) animal models that suggest the association between substance dependence and compulsive overeating; (b) epidemiological studies that confirm the comorbidity between ED and SRD; and (c) neuroimaging studies that reveal the existence of modifications in the reward circuits following binge eating and other eating dysfunctions. The data from the different studies can be integrated into a model based on the consideration of "food addiction" as a specific form of behavioral addiction that could be applied at least to a group of patients suffering from eating disorders.

“…Recently, a revised version based on the DSM, version 5 (DSM-5), substance-related and addictive disorders (SRAD) criteria was developed and validated (YFAS 2.0) [25]. Generally, approximately 5-10% of individuals in community-based samples exhibit indicators of YFAS ‘food addiction' [24,25], though prevalence is higher among individuals with obesity [26] and binge eating disorder [27,28]. The YFAS has been translated into multiple languages to assess the prevalence of addictive-like eating behavior worldwide [23,26,29].…”

Background/Aims: To assess the prevalence and correlates of addictive-like eating behavior in Germany. Methods: The German version of the Yale Food Addiction Scale (YFAS) 2.0 was used to investigate, for the first time, the prevalence of ‘food addiction' in a representative sample aged 18-65 years (N = 1,034). Results: The prevalence of ‘food addiction' measured by the YFAS 2.0 was 7.9%. Individuals meeting criteria for ‘food addiction' had higher BMI and were younger than individuals not meeting the threshold. Underweight (15.0%) and obese (17.2%) individuals exhibited the highest prevalence rate of ‘food addiction'. Addictive-like eating was not associated with sex, education level, or place of residence. Conclusion: YFAS 2.0 ‘food addiction' was met by nearly 8% of the population. There is a non-linear relationship between addictive-like eating and BMI, with the highest prevalence among underweight and obese persons. These findings suggest that ‘food addiction' may be a contributor to overeating but may also reflect a distinct phenotype of problematic eating behavior not synonymous with obesity. Further, the elevated prevalence of YFAS 2.0 ‘food addiction' among underweight individuals may reflect an overlap with eating disorders and warrants attention in future research.

“…Given the strong relationship between low DT and substance addiction, it is also quite possible that low DT is associated with food addiction (FA), which does not have a universal definition, but has been described as ''an abnormal pattern of excessive consumption'' [23]. FA is a controversial topic since its very existence is under debate [24].…”
