Eating more egg yolk is not harmful to muscles, but egg yolk contains higher cholesterol and is not good for health. Generally no more than two egg yolks a day. If there is protein, it doesn't matter if you eat too much.

Adults can only consume about 20g of protein every day, and if they eat too much, they can't be absorbed by the body, so eating too much is a waste. About 3~4 protein is enough, and it mainly supplements energy and water after exercise.
