Our pets rely on us entirely for their nutrition. So if you're making your own judgments, that could lead to a mistake. At the same time, we have more control over our pet's diet than we do with our children or with ourselves, so your vet can tell you what is appropriate for your dog and you can assign them that.

There are times, like after a long day of work, when the thought of an easy drive-through is enticing. But then I remember how crappy I felt when I ate fast food in the past, and it inspires me to head to the grocery store or my local farmer's market and whip up an easy but healthier option.

I save every Christmas card. I keep them all.

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

The mental game of 'holding out,' not eating for as long as possible, at least for me, was a really unhealthy mental place. I would inevitably lose that battle and eat too much in one sitting and end up really mad at myself.
