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.

I battled with my weight as a teenager, partly because there wasn't the information or conversation about how to live a healthy lifestyle.

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.

When I saw contestants fighting for their lives on 'The Biggest Loser,' I realized I just wanted to be healthy - to have fun playing soccer with my son or teaching my daughter to shoot hoops. Then it was so much easier to say no to carbs, soda, or dessert, and the weight just came off.

I'm addicted to a really tough workout. I like to be drenched in sweat when I'm done because I feel accomplished.

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'll have wine or a piece of cake once in a while, but I don't look at it as sliding backwards, even if I go a whole week without working out. I don't dwell on it and beat myself up - I just try to have a healthier day tomorrow.
