Electrical brain stimulation reduces food cravings and calorie intake
In a single-blinded and placebo-controlled randomized crossover study, 14 healthy young men were examined. Their body mass index (kg/m2) ranged between 20 and 25. For 8 days they underwent either a daily electrical stimulation of the right lateral cerebral cortex or a fake stimulation. On the first and last day of either stimulation, the participants were allowed to eat as much as they wanted from a standardized test buffet.
One week after daily brain stimulation, calorie intake was reduced by 14% in comparison with subjects treated by fake stimulation. In addition, the subjects with repeated stimulation of the corresponding brain area reported a decrease in appetite. The results of the study show that direct stimulation of the hunger center is a promising way to reduce calorie intake and appetite at the same time.
