People who are doing fitness, especially professional fitness athletes, will consume a lot of energy due to greater physical activities during the fitness process. People engaged in fitness should keep adequate energy intake, especially in protein. In the process of body-building, protein's supplement is especially needed for muscle growth.

If it is for the purpose of losing weight, it is necessary to calculate the total calorie intake, balance nutrition and supplement protein appropriately.

Especially for dieters, we should not simply emphasize the control of one of carbohydrate, fat and protein, but must achieve a balanced nutrition. Some people overemphasize not eating staple foods and carbohydrates. Of course, it is definitely wrong to eat too much carbohydrate, but if you eat too little carbohydrate, it will lead to obesity and increase the productivity of protein.

In particular, it needs to be emphasized that nutrition should be balanced in the process of losing weight and fitness, and the most important thing is to control the overall intake of energy, which cannot exceed. In other words, only emphasizing eating protein powder will not have the effect of losing weight.
