Yes, but we don't just lose weight. We lose weight through exercise, which is actually a process of consuming fat. When you exercise, the body fat will release energy, thus reducing its volume and achieving the purpose of losing weight. But this is just a simple statement, because you won't burn fat as long as you exercise, which is related to your exercise time, intensity and frequency. I suggest you look at the knowledge about aerobic exercise on the internet. If you can't, you can contact me.
