People who exercise usually eat boiled eggs, which are divided into protein and yolk. The main ingredient of protein is protein, and egg yolk belongs to polyester food. The so-called polyester food can be understood as food with high fat. It is also true that the fat content of egg yolk is as high as 32%. Therefore, for people who want to build muscles, eating too much egg yolk will make the body consume too much fat. Too much fat is the enemy of the fitness crowd. Don't eat egg yolk. Secondly, if the fat content in the body is too high, the muscles will not be exposed, but will only be buried under the fat.
