Disordered eating refers a variety of maladaptive eating behaviours such as dietary restriction, dietary restraint, binge eating, emotional overeating, grazing, and loss of control over eating. In some cases, disordered eating can lead to eating disorders such as anorexia nervosa, bulimia nervosa, and binge eating disorder. In the Healthy Eating and Lifestyle (HEAL) Lab, we study disordered eating across the weight spectrum. Current studies are examining disordered eating in bariatric (weight loss) surgery patients, the impact of weight-related stigma on disordered eating, and predictors of subjective eating binges. We are also developing evidence-based psychosocial treatments with the aim of improving eating behaviours and overall wellbeing.
