A lot of research is now documenting a variety of health benefits from drinking green tea or taking a capsule of green tea extract.
The research reviewed here investigated the effect of epigallocatechin-3-gallate (EGCG), the major active ingredient in green tea, on fat oxidation in obese men (Thielecke F, et al. 2010).
The researchers measured the expenditure of energy in the participants as well as fat oxidation, which is the burning of fat for energy. 300 mg and 600 mg of EGCG were compared with a placebo and also caffeine after they had been taken for 3 days.
It was documented that during the first 2 hours after a test meal the group taking 300 mg of EGCG had 33.3% increased fat oxidation when compared to the placebo group. The group taking 600 mg of EGCG showed an increase of 20.2%, which was less of an increase. It is not always better to take more of a good thing. 300 mg of EGCG increased fat oxidation about the same as 200 mg of caffeine.
300 mg of EGCG would be approximately 5 or more cups of green tea daily depending on the strength of the tea.
If you don’t want to drink that much green tea, one capsule of the formula “Better Green Tea” has approximately the same amount of EGCG as was used in this study.
