Exercise in the early stage of weight loss, and the body will store water after exercise.
Muscle increases, body fat decreases and muscle density increases.
If you haven't exercised before, suddenly start exercising. During exercise, our body will consume a lot of muscle glycogen and liver glycogen, which are the first substances to supply energy during exercise. After exercise, due to the stimulation of exercise, the body generally stores more glycogen than before. Glycogen is stored in water, and every 1g of glycogen storage needs at least 3g of water, so the body will store a lot of water and glycogen in the process of replenishing after exercise. This water has increased your body weight, so you are very heavy.
Of course, if you persist in this situation 1~2 weeks after your body adapts, you will definitely lose weight!
If you don't control your diet, or even eat more, you will gain muscle by increasing exercise.
Generally, many professionals lose fat first and then gain muscle. That is to say, diet is mainly controlled in the early stage, and exercise and strength training are added in the later stage. If you have a lot of fat and exercise, you may turn fat into muscle. Muscle density is higher than fat. Fat and muscle of the same size are heavier, so you may get better.
The essence of losing weight
99% people will judge their fatness by their weight, which is actually wrong. At the beginning (fat stage), you can use your weight as a yardstick to measure your own changes, but in the middle and late stage (slightly fat plastic surgery stage), you still focus on your body shape, and your body shape has nothing to do with your weight, so you pay attention to your appearance, not your weight. Just like a fat man with a weight of 150 kg and a muscular man with a weight of 150 kg, there is a great visual difference.
