Hula hoop is bad and unscientific. Eat well in the morning, eat less at noon, eat low-calorie biscuits at three or four o'clock, eat some fruit at five or six o'clock in the afternoon, and don't eat anything or drink water after eight o'clock. Slender legs just lie in bed at night and stand at 90 degrees to your body for half an hour. If moderate exercise is better, there is no good way to lose face, and people will naturally lose weight if they lose face. This is a cruel way to lose weight.
