Drinking Lipton black tea can help lose weight, but you need to pay attention to the intake and exercise. The caffeine and tea polyphenols in black tea can promote metabolism and lipolysis, while also helping to suppress appetite. However, excessive tea drinking may lead to problems such as caffeine poisoning and poor sleep quality. It is recommended to drink moderate amounts of tea every day, preferably no more than 2-3 cups. Of course, you can’t lose weight just by drinking tea, you also need to pay attention to your diet and exercise properly.
