Applying the developmental model of use disorders to hedonic hunger: a narrative review.

BACKGROUND AND OBJECTIVES: Hedonic hunger (HH) occurs when individuals are driven to consume highly palatable food for pleasure, rather than to satisfy a caloric need. Currently, the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) does not recognize HH as a use disorder. Previous research has noted physiological, neurobiological, and treatment similarities between HH, binge eating behavior and substance use, leading to the speculation of the existence of food addiction (FA). The purpose of the current review was to explore the literature on the developmental similarities between substance use, HH, binge eating behavior, and other use disorders to provide more evidence for the recognition of FA as an official use disorder, to add to the evidence in favor of a developmental model of use disorders, and to inform the development of interventions that target modifiable symptoms associated with use disorders.

METHODS: We provide a narrative review of the literature on developmental factors associated with both HH and substance use.

RESULTS & DISCUSSION: Adverse childhood experiences and attachment have been previously linked to both substance use and maladaptive eating behaviors. Adverse childhood experiences are linked with insecure attachment and emotion dysregulation, which is linked with compulsive behaviors and substance use. Clinical and research implications are discussed in terms of a developmental model of use disorders and the formal recognition of FA in the next edition of the DSM.
