Followed by coffee, coffee is my favorite. Caffeine in coffee can excite the brain for at least four hours. However, there are some taboos in quoting coffee: you can't drink coffee on an empty stomach, and you can't drink it after 2 pm, so you will lose sleep at night, and you can't use more than 40 grams a day, which is a burden to your stomach.
The side effects of the tea market are very small. Because tea is rich in tea polyphenols, it is better for the body and more effective for losing weight.
