Background Grape seed extract (GSE) is a natural supplement known for its various health benefits, including anti-inflammatory effect. This study aimed to evaluate the effects of GSE supplementation on inflammatory markers, neuropeptide Y, anthropometric measurements, and appetite in obese or overweight individuals. Methods and materials A randomized, double-blind clinical trial was performed on 40 obese or overweight subjects who were randomly assigned to receive GSE (300 mg/day) or placebo for a period of 12-weeks. Both groups were under a restricted calorie diet (RCD)(similar to 250 kcal lower than the estimated energy requirement). Anthropometric measurements, biochemical biomarkers and dietary intakes were determined during the study period. Results The reductions of body weight, body mass index, waist circumference, and waist to hip ratio were significantly higher in the GSE group compared to the placebo group (P = 0.045, 0.033, 0.029, and 0.021, respectively). Lower levels of neuropeptide Y, tumor necrosis factor alpha, and high sensitivity C-reactive protein were observed in the GSE group in comparison with the placebo group (P = 0.041, 0.001, and 0.034, respectively). Conclusion GSE supplement with a RCD has favorable effects in reducing anthropometric measurements and inflammatory markers in obese or overweight individuals, and may play an effective role in the treatment of obesity.
