But then the show came out, and no one said anything negative about it, and it's funny because from one perspective you could say, 'Oh, he's letting himself go,' but from another perspective, I just don't need that validation I once did.

Actress Kate Winslet is determined to help her daughter develop a healthy body image.
"When I grew up, I never heard positive reinforcement about body image from any female in my life," she said. "I only ever heard negatives. That's very damaging because then you're programmed as a young woman to immediately scrutinise yourself and how you look."
