First, athletes eat eggs. Many athletes eat whole eggs. They won't throw away the egg yolk because the fat content in it is too high. They did it for a reason. Athletes usually train a lot, but eggs contain many things, such as protein, methionine, and many nonmetallic elements, which are not only conducive to absorption, but also conducive to digestion. Their breakfast eggs account for more than half, and the cholesterol content in egg yolk is high, so athletes will not eat a lot of egg yolk. Generally, protein is eaten first, and then an appropriate amount of egg yolk is eaten, which is beneficial to the health.
Second, people who exercise eat eggs and egg whites. Nowadays, many fitness people are not athletes, but to keep fit, so they are different from athletes. When bodybuilders eat eggs, they only eat egg whites, not egg yolks. This is because many carbohydrates are basically on egg white, while egg yolk is fat. What they need for fitness is protein, not fat. After all, they need aerobic training for 20 to 30 minutes to eat an egg yolk, which is equivalent to wasting so much time to lose fat.
Athletes eat a whole egg because their training costs a lot, but the training of bodybuilders is not that heavy. What they need is protein, not fat. Athletes won't eat so much egg yolk. They eat more protein. After all, the cholesterol in egg yolk is high, and they are prone to get sick. They only eat the right amount of egg yolk.
