The presence of muscle soreness may be accompanied by a small increase in body weight. Some patients who have muscle soreness during exercise may find a small increase in weight when they are weighed again. The mechanism of this situation is mainly as follows: 1. It may be caused by muscle edema, many patients will have muscle soreness after exercise, at this time there will be sterile inflammation inside the muscle, it will lead to edema inside the muscle. Once such edema is produced, the patient may have a small weight gain in a short period of time. This is a condition that may be caused by the patient’s failure to adjust the diet. If the patient has muscle pain and is very tired, the patient eats a lot and may gain weight due to the intake of too much high-energy food. 3, this situation may be caused by excessive rest, some patients will take a long rest to relieve pain after muscle pain. There is nothing wrong with this approach, but if you rest for too long, you may not be active enough to cause the deposition of body fat.
