A meta-analysis on the anti-obesity effects of resveratrol.

This systematic review and meta-analysis focusses on the effects of resveratrol on obesity measures. 28 clinical trial shave been compiled. Supplementation ranged from 8 to 3000 mg/day of resveratrol (median 300 mg/day) and duration from 4 to 52 weeks (median 12 weeks). The authors included studies conducted in healthy subjects, or patients with type 2 diabetes, nonalcoholic fatty liver disease, metabolic syndrome, overweight/obesity or patients with schizophrenia or Alzheimer’s disease.

Results showed that resveratrol reduced body weight (weighted mean difference (WMD) = -0.51 kg, 95% Ci: -0.94, -0.09, p = 0.02), BMI (WMD = -0.17 kg/m², 95% CI: -0.32, -0.03, p = 0.02) and waist circumference (WMD = -0.79 cm, 95% CI: -1.39, -0.2, p = 0.009). Conversely, no change has been measured on fat mass. Resveratrol was effective in studies assessing the effects of dosage of 3 months) or in people with obesity.

Therefore, this meta-analysis reports a small but significant effect of resveratrol an anthropometric measures.
