Let's answer this question for you. First of all, you can lose weight by drinking healthy tea, because drinking tea itself can lose weight, because tea not only contains a variety of trace elements, but also can achieve the effect of reducing fat and dissolving fat, so people who often drink tea water will achieve the effect of losing weight, but when drinking tea water, you must choose good healthy tea, not too strong.

In addition, don't drink tea before bed, especially don't drink strong tea. Drinking tea before going to bed has a certain influence on the stomach and intestines, and it will also affect the quality of sleep. Drinking tea water has many benefits to the body, not only can lose weight, but also has other effects, such as improving eyesight, promoting fluid production and quenching thirst. For those who often stay up late, always drink tea and water.

I hope my answer can help your friend.
