Changing Eating Behavior Using Cognitive Training

Changing Eating Behavior Using Cognitive Training: A Randomized Clinical Trial

Obesity is a global health problem. New and more efficient interventions are needed to overcome this disease. This randomized clinical trial aims to evaluate the effectiveness of changing eating behavior using cognitive training. These types of interventions have the role of creating new routines (unconsciously processed), in terms of healthy eating behaviors.

This is a randomized clinical trial with three groups. Participants will be found through social media announcements. The active interventions of cognitive training will be delivered at two groups: one group will receive through hypnosis and the other will receive through food inhibition training (a GO NO GO task). The control group will receive a simple GO NO GO task as an active placebo. The trial will be exclusively online and it consists of five sessions. Participants will complete their tasks on four Zoom sessions. Cognitive, emotional and behavioral data will be taken at four times: before the intervention starts, in the middle (after two sessions), at the end and at two follow up moments: one month and six months after the trial ends.
