Hi Ms. Gee! Is it true that green tea can help speed your metabolism? I've been drinking Enviga green tea drink, because I love the way it tastes. It's a good replacement for soda, because it's carbonated water with green tea, so it still has the fizz, but only 5 calories. But I read on the can that drinking 3 of them can help you burn an extra 150 calories! I was wondering if you know anything about this. I only drink 1 each day but may drink a few more if there's any truth in it!
