Background Resveratrol was found to alleviate consequences of some metabolic disturbances which may be due to inappropriate dietary habits. It decreases mortality, increases insulin sensitivity and improves motor functions; these effects are accompanied by reduced plasma leptin and insulin. Leptin plays a significant role in the regulation of food intake and energy expenditure -elevated level in blood is one of the reasons of leptinresistance and obesity. In this study, the direct effect of resveratrol on leptin secretion from isolated adipocytes was investigated.
