About this trial
The hypothesis is that the increase in dlPFC brain activity via near-infrared spectroscopy-based Neurofeedback (fNIRS-based NF) training based on near-infrared spectroscopy would allow an improvement of the eating behavior, thus promoting a long-term weight loss in obese subjects.
Patients will be trained during a month with 8 NF sessions and results based on clinical data and different questionnaires results will be compared between inclusion and 3 months later
