I have never actually been to AandW or Culvers so im sorry i cannot help with those! But i have been dieting for 3 years now and i still like to go to those other places you've listed You cant actually put them in an order because each restaurant has both good and bad health choices To start off with Mcdonalds obiously salads are a good choice, maybe get a plain hamburger or a GRILLED chicken sandwhich, SKIP the fries and instead get a side salad. Taco bell- they have a whole diet menu you can pick from. stay away from anything with nacho chese or anything fried. soft shell is the best and chicken for meat is the best also. As for KFC any grilled chicken is good otherwise not too much is healthy off their menu, alot of their products are fried. Burger king is the same as Mcdonalds. Grilled chicken sandwhich, plain hamburger, salads, but still no fries There are nutrition facts for all products on each of the restaurants websites also! just look at that and plan your meal before you go to one! ITs what i do and it helps tremendously!
