We always hear : "drink green tea to lose weight" is that true? And how to use it to lose weight? Thank you.

Green Tea. Tea is derived from a tree called camellia sinensis. The leaves contain antioxidant polyphenols which have an anti-carcinogenic effect. The lighter the tea, the less it has been processed. Whit, red & green teas are especially helpful. The linus pauling institute reported a study that suggest extracts from green tea can act as a plant-based alternative for glycemic control. Drinking it.
I don't know . Where that comes from! it contains a lot of caffeine that might cause an insinuation that it "loses weight". There are no quick fixes.
