Tea itself can't lose weight directly, but some teas help to promote metabolism, eliminate fat and improve intestinal function, thus helping to lose weight. Here are some common recommended teas:

1. green tea: green tea is rich in catechins and catechin compounds, which helps to promote fat oxidation and also has antioxidant effects.

2. Black tea: Tea polyphenols in black tea can promote body metabolism, accelerate fat decomposition and burning, and help to lose weight.

3. Oolong tea: Oolong tea contains a variety of natural compounds, which helps to promote metabolism and fat burning, while controlling appetite, thus reducing calorie intake.

4. Herbal tea: Some herbal teas can also promote intestinal peristalsis and digestion, thus improving intestinal health and accelerating the elimination of waste and oil in the body.

However, it should be noted that although tea is beneficial, it should not be consumed in excess, otherwise it may cause adverse reactions and even have a negative impact on health.
