It's summer, and you have enough resources to lose weight. You can eat watermelon every day, but don't eat watermelon at night, because there is too much sugar in watermelon, which will make your body absorb and gain weight at night. Vegetables are the main staple food every day, and a small amount of meat is eaten. After all, you are still young and have no shortage of nutrition. The ratio of meat to vegetables is between 1:7. Don't go to bed early and get up late every day Get up and run for half an hour before 7 am. Try not to stay at home during the day, especially after meals. Try to sleep around 10 at night. You can take a walk in the same place in the room, or you can exercise outdoors. This will definitely help you lose weight in 50 days, but it is recommended to reduce your height to about 150 kg, which is healthier and not too thin! Just my personal opinion! Wish you success!
