Objective: Binge-eating disorder is characterized by recurrent episodes of consumption of large amounts of food within a short period of time, without compensatory purging behaviors. This disease is a major public health issue and is associated with numerous comorbidities, encompassing anxiety and depression. The gut microbiota has been proposed to be an important player in the onset or maintenance of eating disorders.

Rationale: Patients with anorexia nervosa (AN) often present sleep disorders and circadian hormonal dysregulation. The role of the microbiota-gut-brain axis in the regulation of feeding behavior has emerged during the last decades but its relationships with the circadian rhythm remains poorly documented. Thus, we aimed to characterize the circadian clock genes expression in peripheral and central tissues in the activity-based anorexia mouse model (ABA), as well as the dynamics of the gut-microbiota composition.

The role of microbiota in eating disorders has recently emerged. Previous data reported that lipopolysaccharides induce anorexia and a decrease of body weight through the activation of toll-like receptor 4 (TLR4). In the activity-based anorexia (ABA) mouse model, an increase of TLR4 expression in intestinal epithelial cells (IEC) has been described.
