An interventional study of Thai Food-Specific Inhibition Control Training and General Inhibition Control Training in Obesity & Overweight and Obesity (Disorder), sponsored by Burapha University. Enrolling by invitation at 1 site in Thailand. Open to participants aged 18 Years to 59 Years. Per ClinicalTrials.gov, last updated 2026-11-10.
Sponsored by Burapha University · Not applicable, Interventional, and Treatment
This randomized controlled trial aims to investigate the effects of Thai food-specific inhibition control training on psychological, physiological, behavioral, and neurophysiological outcomes in Thai adults with obesity.
A total of 72 participants will be randomly assigned to either a Thai food-specific inhibition control training group (n = 36) or a general inhibition control training group (n = 36). Both groups will receive training five days per week for eight consecutive weeks.
Psychological, anthropometric, and eating-related behavioral outcomes will be assessed at baseline (T0), immediately after the eight-week intervention (T1), and at a four-week post-intervention follow-up (T2). Event-related potential components, including N2 and P3, will be assessed at baseline and immediately after the intervention.
The study will compare changes in outcomes between the two intervention groups over time to determine whether Thai food-specific inhibition control training produces different effects from general inhibition control training.
Background
Obesity is a multifactorial condition involving physiological, psychological, cognitive, environmental, and behavioral factors. Inhibitory control, a component of executive functioning, is involved in regulating behavioral responses to food-related stimuli. Training inhibitory control in response to culturally relevant food stimuli may provide a behavioral approach to improving eating-related self-regulation.
Study Objectives
The study aims to compare the effects of Thai food-specific inhibition control training with general inhibition control training on psychological outcomes, including health-related quality of life, psychological distress, psychological well-being, and self-esteem, as well as physiological and behavioral outcomes, including anthropometric measurements, eating behavior, eating inhibition control behavior, and neurophysiological indicators of cognitive control.
Study Design
This is a two-arm, parallel-group randomized controlled trial involving 72 Thai adults with obesity. Participants will be allocated to one of two intervention groups, with 36 participants planned per group.
Interventions
The experimental group will receive Thai food-specific inhibition control training. The active comparator group will receive general inhibition control training. Both interventions will be conducted five days per week over eight consecutive weeks.
Assessments
The study includes three assessment periods: baseline (T0), post-intervention at eight weeks (T1), and follow-up four weeks after the intervention (T2).
Psychological outcomes will be measured using the Short Form-36 Health Survey (SF-36), Mental Health Inventory (MHI-38), and Rosenberg Self-Esteem Scale (RSE-10).
Eating-related outcomes will be assessed using the Dutch Eating Behavior Questionnaire (DEBQ), Power of Food Scale (PFS), and Eating Inhibition Control Behavior Questionnaire (EICB).
Anthropometric assessments will include body weight, body mass index, and waist circumference.
Neurophysiological assessments will use electroencephalography to examine event-related potential components associated with inhibitory control, particularly N2 and P3, at baseline and after the eight-week intervention.
Statistical Analysis
Descriptive statistics will be used to summarize participant characteristics. Mixed repeated-measures analysis of variance will be used to evaluate the effects of group, time, and group-by-time interactions on study outcomes, with the statistical significance level set at 0.05.
The principal scientific comparison concerns differences in changes between the two training groups over time.

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Participants assigned to the experimental group will receive a Thai food-specific response inhibition training program incorporating food-related inhibitory control tasks. The training is designed to strengthen inhibitory control in response to Thai food stimuli. Participants will receive the intervention five days per week for eight consecutive weeks.
Behavioral: Thai Food-Specific Inhibition Control Training
Participants assigned to the active comparator group will receive a general response inhibition training program that is not specifically focused on Thai food stimuli. Participants will receive the intervention five days per week for eight consecutive weeks.

Start is estimated for Oct 2026; primary completion for Dec 2026, 2 months later.
Of 3,680 non-industry interventional studies with no phase under Obesity, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 43. This study's planned 2 months is below that.
Counting every sponsor, half of 3,843 studies reached it within 22 months; a quarter within 10 and three quarters within 42.
