What type of green tea speeds up metabolism?

Question

tea bag tea?

and specific names

bottled tea?

Answer 1

Green tea is green tea. There is no "type".

Answer 2

All kinds of green tea will speed up the metabolism somewhat, but not to the point where you can expect to lose more than a few pounds a year. A good idea would be to avoid tea bags, and drink loose leaf teas instead - they are of higher quality, and retain more of the caffeine that makes the metabolism speed up.
