Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Participants

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Hypnosis

Hypnosis formed from hypnotic induction (an adapted version from Harvard Group Scale of Hypnotic Susceptibility) together with hypnotic suggestions about a future where they will control their eating behaviors by choosing the low-calorie food instead of dense calorie one.

Group Type EXPERIMENTAL

Hypnosis

Intervention Type BEHAVIORAL

Participants received hypnotic induction with hypnotic suggestions for their eating behaviors.

Food Inhibition Training

Participants will perform an online computer go-no-go task. They will be shown pictures of dense and low-calorie food together with neutral pictures, followed by the instruction to press or not a button when the pictures are framed in a bold frame (dense calorie food).

Group Type EXPERIMENTAL

Food inhibition training

Intervention Type BEHAVIORAL

Training the associations between foods and motor inhibition using a GO-NO-GO computer task.

Control

Participants will perform an online computer go-no-go task. They will be shown pictures of dense and low-calorie food together with neutral pictures, followed by the instruction to press the button to indicate the position of the picture - left or right.
