There is growing evidence that among persons with disordered eating behavior, the identification of an "addictive-like eating" phenotype for some persons could be relevant and improve our ability to design better tailored interventions. This "addictive-like eating behavior" phenotype encompasses different terms or concepts, including "food addiction", "eating addiction", "compulsive eating behavior", and "food craving", but also applies to some persons with binge eating disorder, bulimia nervosa, anorexia nervosa, or binge eating symptoms. Although these terms may theoretically refer to different underlying causes or conceptualizations of addictive-like eating, all agree on the complex and multifaceted public health problem it represents and on the similarities it shares with other addictive disorders in terms of etiology, epidemiology, and treatment. Addictive-like eating behavior can deleteriously impact the patient's outcome and may lead to poorer weight loss evolution, increased prevalence of co-occurring medical and/or psychiatric disorders, and/or lower quality of life. One of the key challenges for the present and future research is to better identify this subpopulation of patients exhibiting this addictive-like eating phenotype, and to identify the psychological/psychiatric factors and biological mechanisms underlying this increased vulnerability to addictive-like eating. Such preliminary knowledge is crucial for enabling the development of interventions targeting these vulnerability risk factors and, ultimately, improving patient outcomes.
