Study Description

Brief Summary

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.

Condition or Disease	Intervention/Treatment	Phase
Overweight Obesity	Behavioral: Hypnosis with amnesia suggestions Behavioral: Hypnosis with cognitive rehearsal suggestions Behavioral: Hypnosis with memory substitution suggestions Behavioral: Hypnosis with induction only	N/A

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.

Arms and Interventions

Arm	Intervention/Treatment
Experimental: Amnesia Hypnosis formed from hypnotic induction (an adapted version from Barber Suggestibility Scale) together with hypnotic suggestions to experience amnesia for the food pictures they had just seen.	Behavioral: Hypnosis with amnesia suggestions Participants received hypnotic induction with hypnotic suggestions for their eating behaviors.
Experimental: Cognitive Rehearsal Hypnosis formed from hypnotic induction (an adapted version from Barber Suggestibility Scale) together with hypnotic suggestions about a future where they will control their eating behaviors.	Behavioral: Hypnosis with cognitive rehearsal suggestions Participants received hypnotic induction with hypnotic suggestions for their eating behaviors.
Experimental: Memory Substitution Hypnosis formed from hypnotic induction (an adapted version from Barber Suggestibility Scale) together with hypnotic suggestions about a past where they have always controlled their eating behaviors.	Behavioral: Hypnosis with memory substitution suggestions Participants received hypnotic induction with hypnotic suggestions for their eating behaviors.
Placebo Comparator: Control Hypnosis formed from only hypnotic induction (an adapted version from Barber Suggestibility Scale).	Behavioral: Hypnosis with induction only Participants received only hypnotic induction.

Outcome Measures

Primary Outcome Measures

Change in Eating Behavior [The intervention is delivered in one session. The outcome is measured: immediately pre intervention (0-2 min), during intervention and immediately post intervention (0-2 min).]
The number of food pictures chosen by the participant in this single session intervention. The outcome is a measure assessing a change between three time points.
