Red wine provides NO health benefits if you are overweight

It’s been touted as a cure-all for diabetes, dementia, heart disease and even hearing loss, but the miraculous health benefits of red wine cannot be reaped if you are obese, say researchers.
Resveratrol, the active compound found in the skins of red grapes and cocoa, is an antioxidant produced by plants to help protect them from extreme environments and block the effects of ultraviolet sunlight, infections and temperature changes.
The research, published in journal Diabetes, found that although test-tube studies had suggested that resveratrol had an effect on obesity, diabetes, high blood-pressure and blood cholesterol, it had no effect on 24 obese, but otherwise healthy men.
The study, carried out by Aarhus University Hospital in Denmark, gave 12 men high-dose supplements of the substance and 12 men a placebo for four weeks.  Over this period the participant’s insulin sensitivity, blood pressure, cholesterol, and resting energy expenditure were monitored. Researchers found that there was an insignificant decrease in insulin sensitivity and no change in blood pressure, cholesterol and resting energy expenditure.
