Is it ok for a teen to drink green tea?i'm in a diet and i hear green tea can help you lose weight and boost your metabolism.if so how many cups a day

OK - watch caffeine: Green tea has many health benefits and can help with weight loss. In general the more the better but it does have caffeine and too much caffeine can make you jittery, raise blood pressure etc. so limit to 5-6 cups a day and don't drink too late in the day.

EGCG is the active: ingredient in green tea. It will boost your metabolism so theoretically it can help weight loss. Practically speaking it is an aid to help w/proper meal plan and exercise. Peace and good health. EGCG capsules will provide more help than drinking the tea alone and you won't need to use the bathroom so much. See doc for appropriate food plan, possibly low carb and higher protein.
