First of all, on the one hand, we should control our diet, give up snacks, biscuits, nuts (such as melon seeds) and starch (zongzi). We should have a full breakfast and eat less lunch. We should try not to eat meat and rice at the same time, eat less pork, switch to chicken and fish, and stop eating after 5 pm. If you are really hungry, you can chew a cucumber around 4 o'clock and quit cream popsicles in summer.
On the other hand, to strengthen exercise and exercise more, you can choose swimming, which will consume a lot of calories, but be careful not to eat a lot after swimming, otherwise it will be useless.
