“Food addiction” is not a formal diagnosis, but many people report feeling addicted to eating certain foods. Much controversy exists regarding whether people can be addicted to eating certain foods, and if so, whether it is best conceptualized as a behavioural addiction (i.e., addicted to eating) or a substance addiction (i.e., addicted to hyperpalatable ultra-processed foods). In the HEAL lab, we are interested in the controversy regarding food addiction, and the ways in which food addiction is similar to, and different from, existing eating disorders (e.g., binge eating disorder). We are also interested in the psychosocial impact of food addiction and psychosocial interventions to improve food addiction symptoms. We have conducted a systematic review of psychosocial interventions for food addiction and developed a brief intervention combining motivational interviewing and cognitive behavioural therapy for people experiencing food addiction symptoms.
