I found the answers at
www.fitday.com ...you can type in egg yolk or egg white to get the nutritional breakdown. Here's the info for a large egg:
YOLK only:
60 calories, 5g fat, .3g carb, 2.8 protein
WHITE only:
16 calories, 0g fat, .3 carb, 3.5 protein
Eggs are a perfect food for atkins if left whole. On induction you should be striving for a ratio of 65% fat, 5% carbs, and 30% protein.
