Changing Eating Behaviors of Healthy Adults Through Hypnosis

November 25, 2019 updated by: Comsa Loana, Babes-Bolyai University

Eating Behavior - Choice or Reconstruction of Past Experience? Changing Eating Behaviors of Healthy Adults Through Hypnotic Suggestions

There is a lot of research on weight loss. In spite of the research on the subject, obesity is a growing disease all through the world. The results of recent reviews and meta-analyzes show that psychological interventions had small effect on weight loss. The investigators propose a different approach to changing eating behaviors with relevance to weight management and hypothesize that participants in the active interventions will significantly improve their eating behaviors than the ones in the control group. The results will improve the psychological interventions for weight loss.

Detailed Description

This is a randomized clinical trial consisting of four groups. According to the concept of Free Will, the decision of action is taken before being acknowledged and is made following the reconstruction of previous experiences. It can be inhibited immediately (max 100ms) after awareness. The investigators want to intervene based on this model using hypnotic suggestions to change eating behaviors. Participants were found through social media announcements. Three groups receive one session of hypnosis with induction and different suggestions and the control group receives only induction. The eating behavior is measured through computer tasks in which participants have the option to choose pictures of food. The task is performed before, during and after hypnosis and the measurements of eating behavior are taken at all three times.
