About this trial
This project tests whether individuals with overweight or obesity and high craving can learn to change their brain response to food cues using neurofeedback, to impact their craving and eating behavior.

Treatments tested in this trial
Experimental feedback
DeviceParticipants provided with feedback of target brain activation patterns (e.g., thermometer) and will be instructed to try to change the feedback (e.g., decrease the thermometer).
Control feedback
DeviceParticipants provided with control (sham, yoked to another participant) feedback (e.g., thermometer) and will be instructed to try to change the feedback (e.g., decrease the thermometer).
Treatment groups
Trial outcomes
Primary outcomes
Change in craving network strength during transfer runs
Craving network strength will be measured during transfer (i.e., no feedback) runs and compared across scan sessions.
Change in Food Craving Inventory Mean Score
Food Craving Inventory has 28 items rated 1-5 and overall mean is calculated, range 1-5 with higher score indicating higher craving. FCI will be compared between baseline and 1 month follow-up.
Change in Automated Self-Administered 24-hour (ASA24®) Dietary Assessment Tool Healthy Eating Index (HEI).
ASA-24 HEI is scored 0-100 with 100 indicating healthier diet and composite scores examined to interpret the overall score. HEI will be compared between baseline and 1 month follow-up.
Change in craving network strength during resting state runs
Craving network strength will be measured during resting state runs and compared across scan sessions.
