Titanic actress Kate Winslet, who just gave birth to her first child last October, says she has to lose weight or her career will suffer. "It's so insane and bloody boring and I despise myself for it, but I am trying to diet," she tells Radio Times magazine. "I constantly wave the flag of 'Don't go on diets because they're rubbish,' but I'd like to get a bit of the baby weight off or I won't work. What annoys me most is the more terribly thin and fit actresses we have, the less real our films become, which is sad. Thank God for the British ones. They don't care what shape you are."
