There will definitely be changes. After all, it is 20 Jin. But the overall physical change depends on whether the people who lose weight are all fat. Some people lose weight by dieting, but they only lose water and muscle, not fat. Therefore, if you want to lose weight correctly, you must use the right method. Aerobic exercise+anaerobic exercise is the best combination. Not only can you lose fat effectively, but you can also keep fit. This is a healthy way to lose weight. There is no shortcut to losing weight, but exercise is king ~
