Drinking green tea may help you stop piling on the pounds by limiting how much fat is absorbed by the body, scientists say.
Researchers found a compound in the herbal drink slowed down weight gain in a study on mice.
Crucially the mice were already obese at the start of the study from Penn State university.

Research author Joshua Lambert, said, “Our results suggest that if you supplement with EGCG or green tea you gain weight more slowly.”
The researchers, who released their findings in the online version of Obesity, fed two groups of mice a high-fat diet.?
Mice that were also fed Epigallocatechin-3-gallate (EGCG) – a compound found in most green teas, gained weight 45 per cent more slowly than the other mice.

In addition to lower weight gain, the mice fed the green tea supplement showed a nearly 30 per cent increase in fecal lipids, suggesting that the EGCG was limiting fat absorption.
‘There seems to be two prongs to this,’ said Lambert.?
“First, EGCG reduces the ability to absorb fat and, second, it enhances the ability to use fat.”

The green tea did not appear to suppress appetite. Both groups of mice were fed the same amount of high-fat food and could eat at any time.
“There’s no difference in the amount of food the mice are eating,” said Lambert.?
“The mice are essentially eating a milkshake, except one group is eating a milkshake with green tea.”?

A person would need to drink ten cups of green tea each day to match the amount of EGCG used in the study, according to Lambert.
However, he said recent studies indicate that just drinking a few cups of green tea may help control weight.
“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,”said Lambert.

Lambert said that other experiments have shown that lean mice did not gain as much weight when green tea is added to a high fat diet.?
However, he said that studying mice that are already overweight is more relevant to humans because people often consider dietary changes only when they notice problems associated with obesity.
“Most people hit middle age and notice a paunch; then you decide to eat less, exercise and add green tea supplement,” said Lambert. ?
