I hate green tea. So I do not drink it. I had good weight loss results on karkade red tea, it contains hibisсus,plus I drank Indian herbal blend, and also when I attended London Weight Management clinic, they told there that tea tones you up, but people who are prone to swelling and have big body weight, need to drink it in small quantities. not more than a cup per day and in the morning. one must not drink tea before going to bed, especially green one.
