I saw a great article on BodyBuilding.com about the effects of Green tea. Just like you heard in the Snapple commercials, it comes down to epigallocatechin-3-gallate or EGCG. There is research that these ingredients in Green Tea lead to increase in the body’s ability to burn fat.
I recently started substituting green tea for coffee and the effects have been really positive. I feel more alert and my metabolism has noticeably increased. Unfortunately, it does lead to more restroom visits.
