Summary

This study tests whether a wearable device that delivers mild electrical stimulation to the brain, called transcranial direct current stimulation (tDCS), can reduce appetite and binge eating. Adults with binge eating tendencies will use the device at home twice daily for four weeks, with half receiving real stimulation and half receiving a sham. Researchers will measure changes in appetite, eating behavior, and body composition to see if this approach could be a practical, non-drug way to manage cravings.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
transcranial direct current stimulation (tDCS) delivered via a wearable scalp device
What this could lead to
If effective, this could offer a drug-free, at-home option to help manage appetite and reduce binge eating tendencies.
What could go wrong
The trial is early and uses self-administered stimulation, which may not work for everyone. Possible side effects include scalp discomfort or tingling.
