Read our Obesity research guide →This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This study explores whether transcranial direct current stimulation (tDCS)—a gentle, non-invasive technique that uses electrical currents to stimulate specific areas of the brain—can help prepare people for bariatric (weight loss) surgery. The goal is to improve eating behavior and help people maintain their weight loss results after surgery.
Weight loss surgery is very effective at helping people with severe obesity lose weight, but about 40% of people struggle after surgery because they return to unhealthy eating habits. Researchers want to see if brain stimulation beforehand can strengthen self-control around food, making surgery outcomes more successful and lasting.

If you enroll, you'll receive 20 sessions of non-invasive brain stimulation over 4 weeks (typically on weekdays). During each session, special electrodes will be placed on your scalp to deliver gentle electrical stimulation to areas of the brain that control eating behavior. Some participants will receive active stimulation, while others will receive placebo (sham) stimulation, and neither you nor the researchers will know which group you're in during the study.
