Eat two meals a day, and don't eat greasy food, fried food, cold drinks or drinks. Run three times a week. First walk for three minutes to warm up, then run for 4-5 kilometers, which takes about 40 minutes to complete. After running, you will be hungry. Eat two bananas and two eggs. Then remember not to eat for an hour and a half, and don't eat anything after 8 pm, except water, if possible. You can lose 4-5 A Jin months. Walk for 60 minutes if you can't run. Running too fast will thicken your legs, so jog.
