Yeah, and unfortunately that's the pitfall of fast food, most of it is lacking in nutrition if not outright horrible for you, hence why I try to limit it to once or twice a month, usually after a blood donation just to get something in me quickly and start regenerating what I just gave.
Panda Express is an exception for me though, there's more sustenance in a lot of their dishes then people give it credit for. My favorite dish for instance, Kung Pao Chicken, is pretty heavy on the onions, peppers and zucchini, so it's high in fat but also high in other nutrients.
