Is there any truth to the statement that green tea is a metabolic enhancer?

Question

If so, does it have to be straight, or can it be sweetened with honey?

Answer 1

Only in the sense that it increases heartrate a small amount.

The increase in metabolism isn't big enough to be significant in a serious weight loss program, any more than turning off one light bulb is going to be noticeable on your electric bill.

Answer 2

I know that theres this new tea called Enviga and it says that if you drink 3 cans a day it can increase your metabolism by burning 60-100 calories per day. Though that also could be just some advertisement, it tastes pretty good though. Made by Coke
