I wonder how you control your diet. If you have a big appetite because of running, the weight loss effect will be greatly reduced. When you say you eat less, it doesn't mean you eat less calories. A bowl of rice (2 Liang) is 350 kilocalories, and it takes 40 minutes to run before it is consumed. If you eat more than two bowls of rice because of running, it's basically a waste of time.
Besides, "jim87663" upstairs is incorrect. It is true that consuming 1 g glycogen will consume 4 g water, but exercise does not consume glycogen first and then fat, but glycogen metabolism and fat metabolism are carried out at the same time. In fact, fat metabolism needs the by-products of glycogen metabolism to participate in the reaction. For aerobic exercise, the aerobic metabolism of glycogen is dominant in the first 20 minutes, but after 40 minutes, fat metabolism will become the main energy supply mode, and after 1 hour, fat metabolism can even account for 90% of the total energy supply.
In addition, the weight must be weighed regularly, otherwise there is no significance of comparison. Weighing after running is very inaccurate. Maybe drinking an extra bottle of water in the middle of running will have a great impact. I suggest you get up every morning and weigh yourself after urinating. At this time, your weight should be the lightest in a day. Record your weight every morning, and after a few weeks, you will see the pattern.
That's all. There is nothing wrong with your exercise. Pay attention to diet and the time to weigh yourself. I wish you success!
