Set reasonable goals; not something vague and unrealistic like "I want to be super-model skinny." I always had visions of very thin actresses in my mind when I was at the gym and it seemed so unattainable that I would quit any health regimen before it even got off the ground. But when I changed my mindset to focusing on making the healthiest choices possible for myself, it was a lot more realistic, more attainable, and then the results were visible.

Sally Field looks amazing in general, never mind her age! She's a phenomenally talented actress and has had a career spanning so many decades.

We talk a lot on 'Biggest Loser' about how fitness is a natural antidepressant, how it burns off stress. What I like about running is that it gives me time alone. I'm always busy, with people at work, with my kids. I love getting out for a run by myself and just listening to my music.

I recommend that people try new stuff or take new fitness classes all the time. It's important to mix up your routine, not only for your body, but also for your mental state.

If you're sitting in front of the TV, you can't have ice cream. But if you're running around all day, then yeah, you can.

I save my dreams and hopes for my kids. When I'm making a wish under a bridge or tunnel, it's always for them.

I keep track of my body by how my jeans fit—and how I feel.
