Brain stimulation plus thinking-skills training to reduce impulsive eating and weight in veterans with obesity
Transcranial Direct Current Stimulation (tDCS) with Cognitive Training to Reduce Impulsivity and Weight in Veterans with Obesity: A Clinical Trial
This project tries gentle brain stimulation together with thinking-skills exercises to help veterans with obesity reduce impulsive eating and lose weight.

What this research studies
You would receive short sessions of noninvasive transcranial direct current stimulation (tDCS) aimed at the prefrontal cortex while doing computer-based exercises that train decision-making and self-control. Treatments are delivered daily for several consecutive days and the protocol includes a sham (inactive) comparison so effects can be compared. The program pairs stimulation with tasks such as the balloon analog risk task to practice executive control during stimulation. Researchers will track changes in impulsivity, appetite-related behavior, and body weight over follow-up.
Who could benefit from this research
Good fit: Ideal candidates are veterans with obesity who report impulsive or disinhibited eating and who can attend in-person treatment visits at the study site.
Not a fit: People without impulsivity-related eating problems, those currently enrolled in conflicting weight-loss interventions, or those unable to come for onsite visits may not receive benefit from this specific protocol.
Why it matters
Potential benefit: If successful, this approach could help veterans improve self-control around food and achieve greater weight loss than standard approaches alone.
How similar studies have performed: Previous small studies show tDCS and cognitive training are safe and can improve executive function, but combining them for weight loss is relatively new and not yet proven.
