Brief Summary
Obesity is a major public health problem and Binge eating disorder (BED) is very frequently observed in patients considered for weight loss surgery and seems to influence their outcome critically. Literature highlights a global emotional overload in individuals with BED, but few are known on the mechanisms involved. The purpose of this study is to fill this gap by comparing the neurofunctional profiles of emotion regulation between patients suffering from obesity, with or without BED and healthy participants during the performance of emotion regulation tasks. Results may help to understand the neural bases of the impairments observed in patients with obesity, with or without BED, which may in turn help to propose, in the long term, potential new therapeutic approaches.

Outcome Measures
Primary Outcomes (3)
fMRI activations during an emotional regulation task (a cognitive reappraisal task)
The participant either reappraises or passively watches negative or neutral pictures and rates his affect (visual analogue scale: 0 to 10, high scores mean negative feelings).
Day 0
fMRI activations during the inhibition of an ongoing motor response under an emotional condition (emotional stop signal task)
The participant is presented with a series of images comprised of neutral, positive, and negative categories and is instructed to categorize the images according to their valence (Go trials). Some trials include a stop signal indicating that the participant should inhibit his behavioral response and associated emotional reaction (Stop trials).
Day 0
fMRI activations during the performance of an emotion regulation task (an emotional Stroop task)
The participant is asked to count how many numbers are presented on the screen. Numbers may match the value of the number (congruent condition) or not (incongruent condition). The numbers are preceded by emotional stimuli (negative, positive, neutral). The participant also views the emotional stimuli pictures without counting numbers (view condition).
