Sarah doesn't strike me as the type of girl who would sit around eating doughnuts between scenes, and even if she was, she's in practically every scene in every episode in every season. Considering the schedule that she worked, plus how little she is to begin with, there was never any real danger of her gaining weight. Shame, to. Very few people can pull off the Audrey Hepburn look and not just plain emaciated, and Sarah ain't one of those few. Somebody should have noticed how thin she was, taken away her salads, and make her eat some real food for awhile. Maybe Nicholus should have shared his meals with her. They would both have benefited.
