It takes half an hour to turn the hula hoop before the human body starts to consume calories, and so does walking. . .

I have a suggestion. No matter what exercise you do, don't drink water immediately after exercise, let alone eat. Don't drink water for at least 15 minutes, and take a sip. You can't eat for two hours. Otherwise, what you eat will produce three times as many calories. If you feel hungry before exercise, you can eat a few thin biscuits and don't mix too much water, otherwise you will easily get appendicitis.

Try ... persistence is victory! !
