There is no evidence to suggest that eating four eggs a day will harm the body. Eggs are a great vegetarian source of healthy fats, protein, and carbs as well. This makes them a filling and nutritious addition to any meal. That said, they pack about 80 calories each. Try separating your yolks from your whites to limit your macronutrient consumption. Egg whites carry a more concentrated protein content, making them best for muscle growth.
