I found this regarding egg nutrition:
The white of a large egg, or about 1-1/4 ounces, has 16 calories, 3 g of protein, 2 mg of calcium, 4 mg of phosphorus, 55 mg of sodium, 45 mg of potassium, the weensiest little bit of riboflavin, and no fat, cholesterol, or carbohydrates.
The yolk of that egg weighs about 2/3 of an ounce, and has 59 calories, 3 g of protein, 5 g of fat (2 of which are saturated), 212 mg of cholesterol, 23 mg of calcium, 81 mg of phosphorus, 7 mg of sodium, 16 mg of potassium, very small amounts of iron, thiamin, and riboflavin, and no carbohydrates.
Depending on how many eggs you eat that can add up to quite a bit of fat. I know of a lot of people who will eat 3- 4 egg whites and one whole egg a day.
