Scientists turn white fat into obesity-fighting beige fat

(Washington State University) Washington State University scientists have shown that berries, grapes and other fruits convert excess white fat into calorie-burning "beige" fat, providing new strategies for the prevention and treatment of obesity.
In the study, mice were fed a high fat diet. Those receiving resveratrol in amounts equivalent to 12 ounces of fruit per day for humans gained about 40 percent less weight than control mice. Resveratrol is a polyphenol, a type of antioxidant found in most fruits…
Professor of animal sciences Min Du and visiting scientist Songbo Wang demonstrated that mice fed a diet containing 0.1 percent resveratrol were able to change their excess white fat into the active, energy-burning beige fat.
"Polyphenols in fruit, including resveratrol, increase gene expression that enhances the oxidation of dietary fats so the body won't be overloaded," said Du. "They convert white fat into beige fat which burns lipids off as heat - helping to keep the body in balance and prevent obesity and metabolic dysfunction."
