Kate Winslet

Having weighed more than 13st at school, she earned the nickname Blubber and was mercilessly teased. In 1992, she realised she was being cast for her size and lost 3st inside 12 months, leaving her a healthy 10st. But two years later she convinced herself the industry would grant her entry only if she was skinny. She existed on only an apple a day and her weight plummeted to 7st 10lb. In 2003, while pregnant with her second child, Joe, she gained nearly 4st. She lost this following an Oriental face-reading diet — where an analysis of skin, hair and eyes determined the best way for Kate to shed the pounds. Kate ate no red meat or milk, instead filling herself on chicken, potatoes, salad and butter. One tuna salad: 386 cal. One portion roast chicken: 255 cal. One large baked potato: 176 cal. One tbspn butter: 102 cal. Total: 919 cal.
