You can't go wrong with some nuts. The key word is 'some.' Eat them one at a time, not by the handful.

I slice up a ton of cucumbers, celery, carrots and red and yellow peppers. Keep them in your fridge so you always have something handy to curb your snack attack.

When people say, 'Hey, wanna come to our house for dinner?' I say, 'Yeah, what should I bring?' They say, 'How about the dessert?' I just don't skimp on the dessert. I make it the yummy way it should be made, and then I just don't eat the whole pan.

I love to run, but training can be hard, especially with a family and a crazy travel schedule. I often do sprints with my kids, where they bike and I run along side them so we can 'race' each other for a quarter-mile or shorter repeats.

Quite simply, my diet has and will always be everything in moderation. People look at Olympic athletes and think they must cut out all those things everyone else indulges in, and speaking for myself, I never did.

It's not really about the competition. Your biggest challenge in a race is yourself. You're often racing against time. You're frequently running everything through your mind. You're always competing against preconceived ideas. It's not really the person next to you that you worry about.

At the end of a marathon, it's going to hurt whether you're speeding up or slowing down. You may as well push.
