Radiohead - Fitter Happier Lyrics Meaning

I think this is supposed to reference the novel 1984, for more than one thing. It might not literally be 1984, but there are definately some similarities. The line "fond but not in love", i think portrays Winston's feelings toward Julia. He's fond of her, follows her around and what not, but he no longer feels any love. The opening lines Fitter, happier and more productive, is Winston believing (after extreme torture), that he's become a better man.
Radiohead are fans of 1984 (hence the song 2+2=5), so that's why i make the connection.
