I don't tend to eat at fast food places anymore and when I do, I tend to get the salad. I have, on occasion, ordered a burger and just tossed the bun. Atkins also says to beware of the ketchup (loaded with sugar) and any "special sauces" (also loaded with sugar) that they put on the burgers. Lettuce, mayo and tomato are all fine. A good choice would also be to order a grilled chicken sandwich and toss the bun.
