Most people skip the yolk because it is high in cholesterol, fat, and sodium. But if you consume eggs in limited quantities, follow a healthy diet and exercise regularly, you do not have to worry about cholesterol and fat content.
Whether you’re trying to lose weight or build muscle, you need both cholesterol and fat for several purposes. Cholesterol is essential for testosterone production, which helps increase energy levels and build muscle. It also helps build vitamin D when the skin is exposed to sunlight. Vitamin D helps build bone strength.
As far as the fat in the egg is concerned, it’s mostly healthy. Consuming fats helps keep you warm and makes you feel fuller for longer.
