The first thing people lose on a diet is their sense of humor. Keep it fun. Keep it light.

I had one actress who trained with me and took six Spin classes a week. And all she ate was lettuce and Swedish Fish. When the press asked her how she'd transformed' her body, she said, Oh, I do yoga and hike with my puppy.' That made me laugh. Don't lie about how much you work out, because other women are going to think, I walk my dog, why don't I look like that?

I always advise eating regular meals — a mix of healthy carbs, protein and fruits and veggies.
