Seconded. When I used to cut weight for HS and college wrestling it was considerably easier to plan around fast food and pre-packaged options. Those aren't always awesome choices, but they're highly consistent and I can get accurate counts as to how much calories/protein/fiber/fat/carbs I've had.

Doesn't mean I was eating it 3 meals a day, mind you; still mostly brown rice, broc, and chicken breasts. But I could plan around a lunch at Wendy's, while the local steak house was a crapshoot.
