Light Therapy and Binge Eating Disorder Treatment (BED Light Study)

Interest of Light Therapy in the Treatment of Binge Eating Disorder: Prospective Controlled Randomized Double-blind Trial

Binge Eating Disorder (BED) is the most widespread food behavior disorder, with prevalence three times higher than anorexia. Its pathophysiology remains poorly understood and the investigators have few therapeutic options. Following a review of the literature, the investigators hypothesize that luminotherapy could be an innovative treatment of BED by its favorable effect on triggers of hyperphagic access, circadian disturbances, attention and impulsivity. The study is prospective, interventional, randomized, double-blind, monocentric (HCL). 52 patients with BED will be randomized to an active arm with intensive luminotherapy (1 daily 30 min, 10,000 lux in the morning) versus a placebo arm (<500 lux). Treatment will be delver every day during 30 days. Assessments will take place on D0, D30 and D60. The main objective is to compare the evolution of the number of hyperphagic access before and after treatment between the two groups. Secondary objectives are to compare characteristics of hyperphagic access, bodily concerns, food dependence and impulsivity, mood, anxiety, cognitive and attentional profiles (STROOP, Go / No Go, SST, BART, Prospective Time Estimation Task, Switching Task), liking / wanted for different food categories and carbohydrate metabolism (CRP, glucose, insulinemia, insulin resistance, profile of lipid abnormalities, 25-OH vitamin D3).

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
EXPERIMENTAL: High intensity light therapy; Treatment with light therapy in high intensity (10,000 lux)	Device: High intensity bright light therapy; Treatment with light therapy in high intensity (10,000 lux), daily for 30 days between 6 am and 9 am for 30 minutes. Le device is placed at arm's length (at approximately 50-75cm from the eyes) within the field of vision. The light must bathe the face To ensure the light reaches your eyes, this appliance has a stand that can be set to a variable angle. If subject is sitting higher or standing and the top edge of the appliance is below eye level, the appliance will be placed in a tilted position so that its light points further upwards and reaches the eyes. If subject is sitting at a table or desk and the top edge of the appliance is above eye level. The appliance can be placed in a more upright position.
PLACEBO_COMPARATOR: Low intensity light therapy; Treatment with light therapy in low intensity (<500 lux)	Device: Low intensity light therapy; Treatment with light therapy in low intensity (<500 lux), daily for 30 days between 6 am and 9 am for 30 minutes. Le device is placed at arm's length (at approximately 50-75cm from the eyes) within the field of vision. The light must bathe the face To ensure the light reaches your eyes, this appliance has a stand that can be set to a variable angle. If subjectis sitting higher or standing and the top edge of the appliance is below eye level, the appliance will be placed in a tilted position so that its light points further upwards and reaches the eyes.
