"Only 12% of a typical fast-food burger is meat."

Okay, I am absolutely not a fast food apologist, but this is somewhat misleading. A McDonald's burger patty is 100% beef, without fillers or extenders. This is true of many fast food places.

So, throw away the bun (and order without ketchup if you're seriously avoiding sugars) and you're left with something Atkins friendly, which for me means healthier than most of the cr&p sold in the middle of the grocery store. I'm looking at you, Kashi bars!
