 To date, there has only been one published study examining the relationship between tDCS and food craving. Fregni and colleagues 2008 found cravings to be reduced by anode rightcathode left tDCS and cravings did not increase after anode leftcathode right tDCS. The evidence on the effectiveness of tDCS for decreasing food craving indicates relatively short-lived effects lasting only a few weeks. While this may ultimately limit the utility of tDCS, it may have a place in the prevention and management of obesity.
