Why do you have to use tea powder? Tea is also good. I suggest you drink Pu 'er tea. This is not diet tea. Don't worry about any side effects. Just drink it as plain water. It's best to drink a large glass after dinner every day. You can lose weight healthily without worrying about any rebound. I am a very successful example. I used to weigh 1 10 kg. I started drinking Pu 'er at the beginning of this year. After a year, it was unconsciously reduced to 96 kg in April. I thought I would gain weight in the new year. I don't drink much now I have maintained my weight and lost a catty or two. Of course, you can't always overeat. As we all know, no matter how you lose weight, overeating will never be reduced. Come on! Oh, by the way, Pu 'er tea is not expensive. Don't buy too good Pu 'er tea, because the effect is the same. Why waste money? Come on!
