The Role of the Circadian System in Binge Eating Disorder

Brief Summary

Binge eating disorder (BED) shows prominent circadian features that suggest a delay in circadian phase, and preliminary evidence shows binge eating may be responsive to chronobiological interventions, implicating a circadian system dysfunction in its pathophysiology. What remains lacking, however, is comprehensive knowledge of the characteristics of circadian system dysfunction in BED, and whether this dysfunction represents a therapeutic target in BED. There is therefore a critical need to characterize circadian system dysfunction in BED, and evaluate it as a potential therapeutic target. Without such information, the understanding on the role of the circadian system in BED and its potential as a new therapeutic target will remain limited.
