Abstract The rates of paediatric obesity have risen dramatically. Given the challenge of successful weight loss and maintenance, preventive interventions are sorely needed. Furthermore, since a substantial proportion of individuals do not respond to traditional behavioural weight loss therapy, alternative approaches are required. Psychological treatments for binge eating disorder have been generally effective at reducing binge episodes and producing weight maintenance or modest weight loss in obese adults. Given the strong link between loss of control eating and obesity in youths, binge eating disorder treatment may serve as a viable form of excess weight gain prevention. An adapted version of interpersonal psychotherapy for binge eating disorder is one such intervention that we have considered. A description of the theoretical basis and proposed mechanism is described. Adaptations of interpersonal psychotherapy and other established therapies for binge eating disorder may serve as platforms from which to develop and disseminate obesity and eating disorder prevention programs in children and adolescents.
