Recruiting now · Not applicable · 1 countries · Registry ID NCT05107908
What this study is about
The purpose of this study is to determine how different behavioral interventions designed to alter food perceptions and behaviors affect brain responses to food, eating behaviors, and body weight.
Basic eligibility
Full registry criteria
Treatments and study arms
Active Implicit Priming
Approximately 10-minute behavioral intervention
Control Implicit Priming
Approximately 10-minute behavioral intervention
Food Exposure Task
Approximately 10-30 minute behavioral intervention
Primary outcomes
Percent change in blood oxygen level dependent (BOLD) response from baseline to after the 12-week intervention while viewing visual food cues will be measured using functional magnetic resonance imaging (fMRI), focusing on insula, striatum, and prefrontal cortex.
Food image ratings change from baseline to after the 12-week intervention. Food images are rated on "desire to eat" by visual analogue scale (0-100), with higher scores indicating greater desire to eat.
Food intake change from baseline to after the 12-week intervention. Food intake will be measured as total calories consumed during an ad libitum meal.
