Resveratrol, an antioxidant phytochemical found in the skins of red grapes, red wine, and purple grape juice as well as other foods, has been implicated in a number of possible health benefits, particularly heart health. Emerging research continues to suggest that resveratrol might have anti-obesity benefits. In fact, one recent human cell culture study suggests that resveratrol modifies the growth, development, and function of human fat cells. However, the vast majority of this research to date has been done in rodents or cell culture systems.
A new obesity research study (free to read) examined the potential weight control benefits of resveratrol in a non-human primate (grey mouse lemur) model of obesity. For this study, obesity researchers fed resveratrol to the lemurs for 4 weeks during their winter period of natural weight gain. Changes in body weight, food intake, metabolic rate, hormone profiles, daily activity, and more were examined. The obesity researchers reported that weight gain was suppressed from about 6% to 1% after the addition of resveratrol to the lemur's diet. Furthermore, the addition of resveratrol to the diet for 4 weeks reduced overall food consumption by 13% and increased the resting metabolic rate of the lemurs by 29%.
These are interesting results that continue to support the possible weight control benefits of resveratrol. Based on this new animal study, resveratrol appears to support weight control by reducing food consumption and increasing metabolism, thereby altering the ratio of 'calories in' versus 'calories out' in a beneficial direction.
