The star doesnt rely on fad diets to keep her slim, preferring to put the emphasis on health: "My whole life I've gone backwards and forwards the same 10lb. I can wear clothes from 20 years ago. At my thinnest I'm a couple of pounds under 9st - at my fattest I'm a few pounds under 10st. I've gone through many diets that are also so boring. You stop eating and that's what makes you lose weight - not eating. But as you get older, losing weight doesn't make your body look better. "I eat healthily but not that healthily...as anyone who saw me munching a burger will know. But I don't eat burgers regularly. I don't think people should."
