These two kinds of tea are not effective because they belong to black tea and fermented tea. Drinking green tea is the best way to lose weight! Because green tea contains a lot of nutrients and has a certain ability to decompose oil, I think green tea is healthier. Some people may think that drinking too much green tea is not bitter but sweet. If we insist on comparing oolong tea with Pu 'er tea, Pu 'er tea is less likely to get fat. Because all oolong teas are filled with essence and sugar, they taste sweet. I would like to remind all girls or ladies that if you are afraid of being fat, you'd better drink less oolong tea, because oolong tea is better.
