Title: Transcranial stimulation by direct current for treatment of obesity


BACKGROUND: There are several treatments for losing weight and sustain it. Food intake is controlled by the neurobehavioral pathway influenced by several factors including persistent behavioral patterns. OBJECTIVE: To evaluate the effect of transcranial direct current stimulation in obese patients undergoing different nutritional therapies. MATERIALS AND METHODS: A clinical, control, double-blind study was done from January 2017 to December 2018 including three groups of patients: one undergoing a protein diet and the other two on a hypocaloric diet. One hypocaloric diet group and the protein diet group were subjected to the transcranial direct current stimulation protocol. The other group received only simulated administration of transcranial direct current stimulation. RESULTS: Patients submitted to the protein diet and transcranial direct current stimulation showed a faster loss of weight than the other 2 groups. Patients undergoing the transcranial direct current stimulation protocol, regardless the diet, showed the greatest change in neural circuits. CONCLUSIONS: Nutritional therapy combined with transcranial direct current stimulation for the treatment of obesity has satisfactory results that impact on the regulation of neural circuits involved with eating behavior, resulting in a greater loss of weight, a better emotional control and cognitive development.
