I was definitely one of those people who fell for the fat-free cookies and chips that are loaded with sugar and calories.

I wasn't eating the right kinds of calories. I didn't know about healthy carbs such as brown rice and lentils. Now I eat small meals throughout the day: oatmeal with cinnamon to start, fruit and yogurt as a snack, and vegetables or with chicken or tuna, and a healthy carb, like a yam, for lunch.

With reality TV, sometimes it's amazing chemistry and you get these gems that turn out to be everything you hoped, and the camera loves them and they just blossom on the show. And then sometimes it's not all you envision.

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.

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.

Yoga is my luxury workout. If I'm on vacation or I have a day off, I love a 90-minute yoga class. It's a really strong workout, but it takes a little bit longer.

I have two beautiful children and my husband. The perfect day for me is just to be with them and have fun. We like simple things, you know.
