There's no harm in drinking green tea regardless of your age, but you still need to exercise if you want to lose a significant amount of weight. Exercising (and eating frequently) also speeds up your metabolism, you know.

Also many dont know that water also speeds up your metabolism and it has 0 calories unlike green tea (which has a few but they are minimal) here is a quite funny but informative article on the benefits of water http://trickstutorials.com/index.php?page=content/wpotion
