He ran 10 km and was as tired as a refugee. He can make it to the first 8 kilometers, followed by endless suffering. He walked two kilometers and had a nosebleed. In fact, this has great disadvantages. First of all, running consumes energy, which is beyond doubt and will definitely consume excess fat. However, the efficiency of transforming fat into energy is relatively low and the speed is slow, so it may be too late to provide energy for running, so there is a feeling of energy exhaustion. Secondly, the purpose of running is not just to burn fat, but to send a signal to the body. After completing today's things, the body will correct the needs of physical growth and develop in a direction that can better meet today's exercise intensity. In other words, running on an empty stomach will give the body a signal that "tomorrow" may also encounter the state of running on an empty stomach and need to optimize the body. So this friend's exercise has two functions: first, because he didn't eat, his blood sugar was exhausted, and he would consume fat after running for a while. The second is to send a signal to the body that in order to fully cope with possible hunger, we should reduce muscle (muscle is a big energy consumer), increase fat, increase absorption capacity, increase appetite, and reserve energy for the next famine+painful work. Inside and out, maybe the weight loss effect is not ideal this time. Unless you continue to starve, you may be weaker and it will be difficult to continue training. A good way to lose weight must not be so hungry that you can't continue running. Eat a certain amount of food, so that the speed of burning fat can supplement the needs of exercise in time, so that you have more time to exercise and lose weight safely. And increase your muscles. 1
