Abstract
BACKGROUND: Although some studies have reported significant reductions in food cravings following the single-session of repetitive transcranial magnetic stimulation (rTMS), there is little research on the effects of multi-session of rTMS on food consumption and body weight in obese subjects. OBJECTIVE: We conducted 4-week randomized, sham-controlled, single-blind, parallel-group trial to examine the effect of rTMS on body weight in obese adults. METHODS:Forty-three obese patients (body mass index [BMI] ≥25 kg/m2) aged between 18 and 70 years were randomized to the sham or real treatment group (21 in the TMS group and 22 in the sham treatment group). A total of 8 sessions of rTMS targeting the left dorsolateral prefrontal cortex (DLPFC) was provided over a period of 4 weeks. The primary outcome measure was weight change in kilograms from baseline to 4 weeks. Secondary endpoints included changes in anthropometric measures, cardiovascular risk factors, food intake, and appetite. RESULTS: Participants in the rTMS group showed significantly greater weight loss from baseline following the 8 session of rTMS (-2.75 ± 2.37 kg vs. 0.38 ± 1.0 kg, p < 0.01). Consistent with weight loss, there was a significant reduction in fat mass and visceral adipose tissue at week 4 in the rTMS group compared with the control group (p < 0.01). After the 8 sessions of rTMS, the TMS group consumed fewer total kilocalories and carbohydrates per day than the control group (p < 0.05). CONCLUSIONS: 8 sessions of HF rTMS delivered to the left DLPFC were effective in inducing weight loss and decreasing food intake in obese patients. TRIAL REGISTRATION: Clinical trial registered with the Clinical Trials Registry at http://cris.cdc.go.kr (KCT0002548).
