Binge eating disorder (BED) is characterized by reoccurring binge eating episodes that consist of eating a subjectively or objectively large amount of food over a period of time accompanied by a sense of loss control over eating, in the absence of recurrent compensatory behaviors (e.g., purging). Cognitive behavioral therapy (CBT) is the current gold-standard treatment for reducing binge eating episodes in BED patients. The first-line of recommended CBT treatment is a self-guided intervention called CBT-Guided Self-Help (CBT-GSH). However, for a substantial minority of patients, CBT-GSH fails to reduce binge episodes after treatment. Preliminary findings of the literature suggests that individuals with BED possess deficits in inhibitory control as it relates to food-stimuli. We are studying how inhibitory neurobiological and neurocognitive processes relate to binge eating treatment outcome.
