Moreover, the investigators aim is to recognize subjects suffering from anhedonia (one of the core symptoms of depression, lack of pleasure) and follow how they benefit from the program in order to achieve maintained weight loss. Also, the associations between weight loss, physical activity and musculoskeletal disorders are studied.
