3. They will be individually exposed to the ten different virtual foods assessed as eliciting the highest levels of craving in each of the four virtual environments (kitchen, dining room, bedroom, and café) for a total of 40 virtual situations from lowest to highest craving scores as previously registered in phases 1 and 2. Once in the virtual situation, the participant will be asked to sit at a virtual table where the food is placed. Once the participant sits, the time is measured. During the first 20 seconds, the patient can handle the virtual food by means of the laptop's mouse but cannot eat the food. When time runs out, the levels of craving and anxiety will be assessed by means of visual analog scales that range from 0 (not at all) to 100 (extreme). Virtual environments will be displayed by means of a 3D laptop with specific software that is capable of creating a stereoscopic effect that is duly processed by polarized glasses. Headphones will also be used. This assessment will be conducted in a quiet darkened room to increase the participant's immersion in the virtual scenarios. The therapist will remain behind the patient during the assessment so as not to interfere with the task but to be available in the event a participant requires assistance.
