Some people may be suitable for a reasonable diet to lose weight, while others can't stand it. To lose weight, keep your mouth shut, keep your legs apart, and make time to do some aerobic exercise every day, such as running, skipping rope, swimming and Tai Ji Chuan. If you want to exercise your muscles, you should also do strength training, such as barbells, squats and push-ups. The core of weight loss is exercise metabolism. Those who lose weight by starving will rebound. Of course, you must remember to do a comprehensive stretching and warm-up training before doing exercise to prevent injuries during exercise. Avoid drinking, smoking, staying up late and overworking during weight loss. Being too tired will lead to overwork. Be sure to get enough sleep, don't stay up late playing games, don't eat dessert and drink cold water, eat more vegetables and high-protein foods in your diet, such as fish, chicken breast and eggs, and try not to eat too sweet fruits. Be sure to have breakfast, and be full at eight o'clock for lunch and dinner. Remember not to eat too much, as long as the amount of exercise is higher than your diet.
