The body is very good ah, as long as it is not excessive, do not drink in the morning on an empty stomach is not good for the stomach, and do not drink at night is easy to insomnia. Black coffee to go to the swelling effect is very good. The best way to lose weight Control of food + a small amount of exercise + balanced diet + long-term persistence Personally, I think the black coffee half an hour Hou and then do exercise to lose weight is not a great relationship, you are eating other foods (do not be high-fat and high-sugar on the right) half an hour after the exercise is equally easy to lose weight, the most important thing is that you can insist on doing!
