Why do fitness enthusiasts eat egg whites instead of egg yolks

Fitness enthusiasts usually choose to eat egg whites instead of egg yolks, mainly because egg whites are rich in high-quality protein and have low fat content, while egg yolks contain higher cholesterol and fat. Protein is more suitable for muscle building needs, and egg yolks can be consumed in moderation but the total amount should be controlled.

protein has a high protein content and is easily absorbed by the human body. Every 100 grams of egg white contains about 11 grams of protein, while fat is only 0.2 grams, making it suitable for muscle repair and synthesis after fitness. Albumin and globulin in proteins can quickly supplement amino acids and promote muscle fiber reconstruction after training. Supplements such as protein isolate powder are often made from pure protein to avoid additional fat intake affecting body fat control. Although egg yolks contain nutrients such as lecithin, vitamin A, and vitamin D, the cholesterol content of a single egg yolk is close to 200 milligrams, exceeding two-thirds of the recommended daily intake. Long term excessive consumption may increase low-density lipoprotein cholesterol levels, which is detrimental to cardiovascular health. The fat in egg yolks is mainly saturated fatty acids, with a high calorie density. People in the fat loss period need to strictly calculate their daily intake.

Fitness diet should pay attention to the balance of protein and trace elements. Egg yolks can be consumed 3-4 times a week, combined with dark vegetables to supplement fat soluble vitamins. Low fat and high protein foods such as whey protein and chicken breast can be used as the main source, and cooking should be done by boiling or steaming to reduce oil addition. Special populations such as those with abnormal cholesterol metabolism should adjust their egg yolk intake under the guidance of a nutritionist.
