ABSTRACT

PURPOSE: Impulsivity might contribute to the development and maintenance of obesity and eating disorders. Patients suffering from binge eating disorder (BED) show an impulsive eating pattern characterized by regular binge eating episodes. Novel behavioral interventions increasing inhibitory control could improve eating behavior in BED. We piloted a novel food-specific inhibition training in individuals with BED. METHODS: N = 22 BED patients according to SCID-I were randomly assigned to three sessions of a training or control condition. In both conditions, pictures of high-caloric food items were presented in peripheral vision on a computer screen while assessing gaze behavior. The training group had to suppress the urge to turn their gaze towards these pictures (i.e., to perform antisaccades). The control group was allowed to freely explore the pictures. We assessed self-reported food craving, food addiction, and wanting/liking of food pictures pre- and post-intervention. RESULTS: Twenty participants completed the study. The training proved to be feasible and acceptable. Patients of the training group significantly improved inhibitory control towards high-caloric food stimuli. Both groups reported a significantly lower number of binge eating episodes in the last four weeks after termination of the study. No changes were found in food craving, food addiction, liking, and wanting ratings. CONCLUSIONS: A food-specific inhibition training could be a useful element in the treatment of BED and other eating disorders; however, larger efficacy studies in patient samples are needed to investigate the efficacy of this and similar training approaches.
