1, protein is several times heavier than fat, and body fat rate can be reduced and protein ratio can be increased through exercise. This can improve the bloated state and make you slimmer. But the weight will not necessarily drop.

2, people's weight tends to be stable, there is no way to lose weight immediately. Unhealthy weight loss tends to rebound. In the initial stage of fitness, some changes will take place in the body, and it is normal to be fat at first.

Exercise consumes energy and promotes the oxidative decomposition of fat stored in the body, thus reducing fat. But at the same time, frequent muscle contraction and exertion during exercise will stimulate muscle fibers to thicken and increase muscle mass. In the body, the water content of muscle tissue is much higher than that of fat tissue, so muscle is "heavier" than fat (strictly speaking, on the premise of the same volume). In other words, as long as the muscle "less" increases, it will offset the weight loss caused by the "more" reduction of fat. Eventually, the weight loss before exercise is not obvious.
