If you want to ease the effects of fatty food on your waistline, it might pay to put the red wine to one side and wash your meals down with green tea. A compound in the drink, epigallocatechin-3-gallate (EGCG), significantly slows down weight gain associated with a high-fat diet, a study found. Obese mice on a fatty diet that were given EGCG gained weight 45 per cent more slowly than a control group eating the same food without the green-tea supplement. The mice fed the supplement also appeared to absorb 30 per cent less fat. 
‘There seem to be two prongs to this,’ said Dr Joshua Lambert, a food scientist at Penn State University in the U.S. ‘First, EGCG reduces the ability to absorb fat and, second, it enhances the ability to use fat.’ 
'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 a day to match the amount of EGCG used in the study, Dr Lambert said. But recent research indicated that just a few cups of green tea could help to 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 Dr 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.The study, published in the online journal Obesity, found the green-tea supplement did not suppress appetite, as both groups of mice were fed the same amount of high-fat food.'There's no difference in the amount of food the mice are eating,' said Lambert.
