If you are lazy, you'd better try long-term fitness. Restrain yourself in diet. It is best not to eat dessert at night and avoid it completely. If you have too much fat, you can eat nothing for three days (only drink water for three days). After three days, the diet is light 1 day, and then slowly adjust your daily diet, that is, don't reduce your appetite too much at one time, you must eat breakfast, have a full lunch and not too full dinner. Then gradually reduce the amount of food once a week to cooperate with exercise. You can eat some sweet potatoes when you are hungry (not fat). Don't eat after 8: 30 in the evening. Go to bed early and get up early to have a good quality of life. Don't eat junk food. I've lost 15 kg, so I can relax and eat something good for only one day. Then continue to exercise according to the previous method, and then lose 15kg.
