Fitness can reduce weight, and the main factors affecting weight variables are water, muscle and fat. It should be noted here that what we call "losing weight" every day refers to losing fat, not muscle and water; We often see that a person will lose weight after occasional sweating or exercise, thinking that this is "losing weight". In fact, most of the weight loss here is water.

Secondly, sugar, protein and fat provide heat for human body. Sugar in human body exists in the form of glycogen, including liver glycogen and muscle glycogen, which is the main one related to physical exercise. When people exercise, they first consume muscle glycogen and then subcutaneous fat.

The last consumption is protein; Muscle glycogen in muscle is often consumed after 30-40 minutes of exercise. Therefore, it is meaningless to lose weight only by exercising for 30-40 minutes every day without adjusting the diet structure.

Also, obese people generally have higher fat content, while protein (muscle) content is relatively low. In the process of fitness and weight loss, if you don't interfere with diet, although you lose fat, you may have low protein, decreased immunity and changes in hormone levels.

At this time, if there is not enough protein in the body to support the energy needed by the body, our health will be threatened. Therefore, in the process of fitness and weight loss, we must pay attention to increasing the intake of protein and reducing the proportion of fat intake.

In daily life, protein accounts for 10%- 15% of people's total daily calories, and fat accounts for 20%-30%. Therefore, in the process of fitness and weight loss, we suggest that the intake ratio of protein can be increased to 25%-35%, and the fat ratio can be reduced to 13%- 17%.

Of course, this is not a blind pursuit of online or offline data. It needs to be determined according to the individual situation, and if necessary, consult a nutritionist to obtain a scientific and effective diet plan.

Extended data:

Fitness will definitely use muscles, especially some dieters who will carry out resistance training. Muscle is stimulated and muscle fibers are damaged during training, so muscle will store extra glycogen very wisely to prepare for the coming training.

At the same time, the water content will also increase with the increase of sugar, and the ratio is usually sugar 1: 3 water, both of which will increase the weight.

The influence of sugar and water on weight change is only one big aspect, and other aspects include: bone mineral density increases gradually with muscle training; Changes in certain hormone levels can affect body weight.
