The quantity requirement for supplementing protein is generally one gram of protein per kilogram of body weight per day. So, with your weight and exercise, you need at least 80 grams of protein every day. The weight of each egg is about 60 grams, of which the weight of egg white is about 30 grams, and its water content is generally about 70%, so the crude protein of an egg white is about 10 gram. In this way, if you only use egg white to supplement protein every day, you need to eat about 8 eggs of egg white.

Supplementary answer:

(1) The amount of egg white obtained with 8 eggs is not so scary. Cixi slaughtered hundreds of chickens to eat a plate of chicken tongue soup, which was not scary at all, because those chickens were not thrown away, but rewarded eunuchs. If the water in these egg whites is removed, the income may not be "scary" but very "poor".

(2) The landlord is probably worried about cholesterol, so he only eats egg white, because egg white basically contains no cholesterol.

(3) You can't just see that egg yolk contains fat and cholesterol. In fact, lecithin and other nutrients in egg yolk are not found in egg white. Eating a little egg yolk properly will not increase too much cholesterol, but will make the nutrition more comprehensive and balanced.

(3) Bodybuilding is basically to exercise muscles. Lysine in protein is the most important nutrient in muscle tissue. Therefore, eating more lean meat from chickens, cows and pigs is helpful to the formation of muscle tissue.
