In fact, not only egg white can supplement protein, but some protein powders also have this effect. For example, at the end of the program, the host will give each player a glass of water with protein powder in it. The host didn't give it to the players before or during the game. The athletes drank all the functional drinks in the competition. So is my favorite online celebrity Zhang. When she went to the gym, because she went on an empty stomach, the fitness instructor kindly prepared a few proteins for her to eat after exercise, but did not let her eat on an empty stomach before exercise. So eating after fitness is the best choice.
It can be seen that fitness instructors are professionals, and professionals say that it is absolutely right to eat egg whites after fitness.
