Epigallocatechin gallate (EGCG), an ingredient in green tea, dose-dependently -- in other words, the higher the dose, the larger the effect -- reduces body fat and body weight according to a new study in mice. EGCG as 0.5% of diet: 6.7% lower body weight, 25.4% less body fat

Mice given EGCG as 0.5 percent of their diet, weighed 6.7 percent less after one month (43 grams vs 46 grams) and had 25.4 percent less body fat (19.1 percent versus 25.6 percent) than control mice eating the same diet without the EGCG.

EGCG as 1% of diet: 12.3% lower body weight, 34.4% less body fat

Mice given EGCG as 1 percent of their diet, weighed 12.3 percent less after one month (41 grams vs 46 grams) and had 34.4 percent less body fat (16.8 percent versus 25.6 percent) than control mice eating the same diet without the EGCG.

EGCG reduced food absorption, increased fat excretion

EGCG decreased fat absorption and slightly increases fat excretion.

EGCG alone had no effect on body temperature or calories burned

When checked over a three day period, EGCG had no effect on body temperature or the number of calories burned.

Comment: In an interview, obesity researcher Dr. Abdul Dulloo explains thatit is the combination of EGCG and caffeine found in green tea—not EGCG alone—that increases thermogenesis and metabolism.

One study found that green tea increased daily calories burned by 4 percent.

Another study found that tea drinkers have 20 percent less body fat.

Previous research: Men lose 5.3 lbs drinking oolong tea

A previous study found that men lost 5.3 pounds in three months by drinking oolong tea.

Oolong tea is green tea that has been partially fermented.
