Green tea 'could help fight weight gain'

6 October 2011

Health research has shown that green tea may slow down weight gain and serve as another tool in the fight against obesity.

Penn State food scientists studied mice that were given a compound found in green tea (EGCG) along with a high-calorie diet. They found that they gained weight significantly more slowly than a control group of mice that did not receive the green tea supplement.

Led by Joshua Lambert, assistant professor of food science in agricultural sciences, the study also found that mice who were given green tea showed a nearly 30 per cent increase in fecal lipids, suggesting that the EGCG was limiting fat absorption.

Mr Lambert said that EGCG reduces fat absorption and it enhances the ability to use fat.

He added: "Human data - and there's not a lot at this point - shows that tea drinkers who only consume one or more cups a day will see effects on body weight compared to non-consumers."

According to researchers in Japan, drinking green tea alone is not going to be satisfactory for significant weight loss. Still, green tea can still be quite useful as a weight loss aid.
