I say: 'Eat what you want to eat,' at the end of the day, but if you're not comfortable with yourself then don't go mad and starve yourself. Go to the gym and eat sensibly. You can do walking and running too.
Kids don't need to diet - often it's just puppy fat and it will come off.
Curves are good
Your body changes a lot in your teens. My shape has changed.
I prefer models with fuller figures. It's nice to have curves. My favourite models ever are Marilyn Monroe and Sophie Dahl - they have fantastic, fuller figures.
My body has changed and I've got a fuller figure now. But I am getting lots of work as a model and I'm happy with my new shape.
It's not about weight, it's about being healthy and sensible."
