Summary

This randomized, placebo-controlled, double-blind, parallel-design study aims to evaluate the neurophysiological effects of home-based transcranial direct current stimulation (tDCS) on appetite in adults with binge eating tendencies.

Participants will be randomly assigned to either an active tDCS group or a sham stimulation group. After baseline assessments, participants will self-administer home-based tDCS twice daily for 4 weeks using a wearable wellness device. Appetite, eating behavior, body composition, dietary intake, and psychological outcomes will be assessed throughout the study to evaluate both the acute and chronic effects of repeated tDCS.

Conditions

  • Appetite
  • Binge Eating Behaviour
  • Food Cravings

Interventions

DEVICE

Active Home-Based tDCS

Participants receive active home-based transcranial direct current stimulation (tDCS) using a wearable wellness scalp stimulation device. Active stimulation delivers 1.0 mA direct current for 20 minutes twice daily for 4 weeks.

DEVICE

Sham Home-Based tDCS

Participants receive sham home-based transcranial direct current stimulation (tDCS) using the same wearable wellness scalp stimulation device. Sham stimulation delivers brief current only at the beginning and end of each session to maintain blinding.
