- Brief Summary
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
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.

Group Intervention Description Hypnosis 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. Food Inhibition Training 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). Control 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.
- Primary Outcome Measures
Name Time Method Change in Eating behaviour 2 - Quantity of calories intake Baseline, pre-intervention; in the week of the intervention; 1 month; 6 month. A self reported diary of food in two different day of the week (weekday and weekend day)
Change in Weight Baseline, pre-intervention; immediately after the intervention; 1 month; 6 month. Weight in kg
Change in Eating behaviour 1 - Daily Snacking Baseline, pre-intervention; immediately after the intervention; 1 month; 6 month. A self reported questionnaire of high calorie food frequency
Change in Eating behaviour 3 Baseline, pre-intervention; immediately after the intervention;1 month; 6 month. Self-reported Three Factor Eating Questionnaire. The scale measures three aspects of eating behavior: cognitive restraint (CR), uncontrolled eating (UE), and emotional eating (EE). It has 21 items and the responses are on a four-point Likert scale ranging from 1 Definitely true to 4 Definitely false with three subscales one for each domain. Higher scores indicate greater CR, UE, or EE.
- Secondary Outcome Measures
Name Time Method Change in Self-Efficacy Baseline, pre-intervention; during the intervention (after 2 days), immediately after the intervention; 1 month; 6 month. Self-report - Weight Efficacy Lifestyle Questionnaire. The response is given using a Likert scale in 0 to10 points: 0 for "Not confident at all" and 10 indicates "Very confident". Higher total scores are associated with higher eating self-efficacy and motivation to make positive lifestyle changes.
Change in Motivation Baseline, pre-intervention; during the intervention (after 2 days), immediately after the intervention; 1 month; 6 month. Self-report - Intrinsic Motivation Inventory. The interest/enjoyment subscale is considered the self-report measure of intrinsic motivation; The responses are made using Likert type ratings from 1 - not at all true to 7 very true. Higher total scores indicate higher intrinsic motivation.
Change in Eating Preferences Baseline, pre-intervention; immediately after the intervention; 1 month; 6 month. Self-report - A three-point Likert scale created by authors about the preferences of high-calorie food. Higher scores mean a high preference for high-calorie food.
Change in Eating Intentions Baseline, pre-intervention; during the intervention (after 2 days), immediately after the intervention; 1 month; 6 month. Self-report - A three-point Likert scale created by authors. Higher scores indicate a stronger desire to eat high-calorie food.
Change in Positive and Negative Affect Baseline, pre-intervention; during the intervention (after 2 days), immediately after the intervention;1 month; 6 month. Self-report - Positive and Negative Schedule (PANAS). The responses are made using Likert type ratings from 1 - Not at all, to 5 Very much. Higher scores on negative affect representing higher levels of negative affect and higher scores on positive affect representing higher levels of positive affect.
