airam i'm guessing it was the diet and not the tea that made you lose weight.... I was advised to start on green tea after my stroke, basically if you think about it, westerners smoke, and have a lot of strokes, the chinese smoke even more, yet are a lot physically healthy than us, it's also their diet, but green tea is rich in antioxidents which go to the unhealthy parts of your body to help them, not saying it cures illnesses, but it does help keep colds e.t.c at bay, I have mild green tea with a hint of Lemon, which you can buy from Tesco, you can also buy regular green tea there also, but if you're just starting out it's an aquired taste, i'd start on the light version and work your way up the strenght's as you get used to it, hope this helps!
