Protein is important and hard for me to get in a hurry. We're busy. I don't always remember to thaw the chicken for dinner. I always have eggs, and they're light and satisfying. I never feel stuffed at the end of it.

I enjoyed every bit of my swimming career. I think that's the most important advice - to enjoy what you do

It really was my brother who got me involved in swimming. I wanted to be just like him and do everything he was doing.

Tennis is interesting because the women are almost more popular than the men. In the U.S. Open, women even get exactly the same money as the men.

I started swimming when I was four because my brother wanted to join a swim team, and I wanted to do what he did. They said I had to be six, but if I could swim a lap, then I could participate. So I swam a lap, and the rest is history.

At 4, I joined a summer rec team called the Sugar Bears.

A great way to get all the right nutrients is to make a colorful plate - mix of good vegetables, carbohydrates, and protein. If you notice all your vegetables are green, change it up and add another color for a variety of benefits in one meal.
