It's rich, it's creamy, it's delicious ... and, like all good things in life, it's loaded with fat and calories. One cup of Egg Nog can set you back 343 calories and 19 g of fat, and that's without the booze. With a shot of rum, that number jumps to well over 400 calories per cup. Make it like my mom makes it with whipped cream and so much rum that you can hardly taste anything else? Well, I can only imagine.

Light egg nog is better -- but not by much. A cup has 280 calories and 4 g of fat.
