Abstract Title:
The effects of grape seed extract (Vitis vinifera) supplement on inflammatory markers, neuropeptide Y, anthropometric measures, and appetite in obese or overweight individuals: A randomized clinical trial.
Abstract:
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)(~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.
