This situation you encounter belongs to fat softening, which is an intermediate process to lose weight. First of all, talk about the principle of softening:

Human waste is mainly transported from all parts of the body through the network system of meridians and blood vessels, and then discharged from the body after being treated by corresponding organs. Except the food residue in the digestive system, the garbage in the body will be discharged from the intestine in the form of stool, and other garbage in the non-digestive tract must be discharged in the form of liquid urine or sweat.

Adults lose weight, because the fat accumulates for too long, it gradually forms particles or plates, which makes these garbage unable to be discharged from the body through the garbage transportation channel of the human body. The body must first fill these solid wastes with water, dilute them into smaller particles, and then excrete them with the transport of body fluids.

Usually, the darker the skin, the stronger the body, indicating that the situation of fat accumulation is also very serious. Due to the constitution of lung deficiency, the water content of most garbage is low. Therefore, in the process of physical recuperation, it is more prone to a large number of water filling phenomena. The parts that used to be strong began to soften gradually, and then gradually became thin.

So don't worry, it will be good for your health to keep exercising.
