My old food wasn't selected for its great taste or satiety, but since my family didn't cook I was sincerely at a loss of how to survive without frozen convenience foods and restaurants. After a proper plate of roast beef and sweet potato there was no looking back really. The only real "cost" is the foreplanning--I don't eat spontaneously but even that was stressful. I prefer to have Mon-Fri sorted so I can think about other things.
