Beef has Protien and they actually beat McDonalds in that regard. Comparing a sack of ten White Castle Cheeseburgers to four McDonald Double Cheeseburgers:

10 WC Ch Burgers . 700 grams Protien . 1600 Calories . 200 mg Cholesterol . 3600 mg Sodium
4 McD Doubles . . . . 100 grams Protien . 1760 calories . 320 mg Cholesterol . 4600 mg Sodium

Add a Coke and you've already exceeded the USRDA calorie allowance for the day.
