I think the most effective thing is dieting. I lost 20 kilograms in this way for half a year. At first, I ate bit by bit to reduce my stomach, and then I began to lose weight. I have a full breakfast every day. Chinese food does not eat staple food, greasy food, potatoes, ice cream, sweet potatoes, noodles, sesame sauce, salad dressing and other high-calorie foods. I ate boiled vegetables in the evening, and I stopped eating after six o'clock in the evening, and I didn't eat when I was hungry. Take a walk for an hour or two after dinner every day, or walk for more than half an hour (not one minute 100 step). It doesn't work for the first month, but you will lose weight if you stick to it. I control myself to lose two pounds a week, otherwise my body can't stand it. Also, be sure not to eat more just for friends' parties, but to eat less at all times.
