Of course, you eat egg whites. There is a lot of whey protein in egg white, which is also the nutrition needed for human muscle growth. In addition, creatine is more important and necessary for muscle growth. Eat lean meat in moderation, which contains a lot of creatine. Drink plenty of water at ordinary times, and don't overeat, otherwise you will have no strength during training, and your physical ability will only be produced in a moderate state of harmony, that is, when you just have enough to eat and feel nothing.
