Drinking green tea is beneficial to lose weight, but it is difficult to achieve a certain weight loss effect simply by drinking green tea. It is still necessary to achieve a certain effect by reasonable diet and strengthening exercise. Tea polyphenols, theanine and vitamin C contained in green tea can effectively help digestion, reduce blood fat and lose weight, but this effect is not particularly obvious. If you just drink green tea and eat a lot of high-calorie food, you will not be able to lose weight without exercise. Drinking green tea can only be used as a means to help lose weight.
