Isn't that the kind of not-valuing-food mentality the article talks about? Your reheated vegetables are going to be overcooked and your fried-and-sauced Chinese will get soggy, but they're still edible. They still provide sustenance.

I love fine food, but not every meal has to be amazingly delicious. In the end, it's about putting energy into your body, so why not lower your standards a bit and eat last night's soggy orange chicken for lunch?

As an aside, you can improve your leftovers with proper preparation. For example, yaks_hairbrush above claims that chicken strips and fries don't reheat well, but I reheat fried foods in the oven regularly, and they're perfectly edible.
