In the 10 cities with the nation's highest obesity rates, the direct costs connected with obesity and obesity-related diseases are roughly $50 million per 100,000 residents. And if these 10 cities just cut their obesity rates down to the national average, all added up they combine to save nearly $500 million in healthcare costs each year.

This year, 1.7 million young people will be participating in Olympic and Paralympic sports in their communities-many of them for the very first time. And that is so important, because sometimes all it takes is that first lesson, or clinic, or class to get a child excited about a new sport. This summer, together with our children, we can support Team USA not just by cheering them on, but by striving to live up to the example they set.

My dad was a pump operator at the city water plant, and he didn't earn much money. But he was determined to pay whatever tiny part he owed for my tuition on time every month. So even though he had multiple sclerosis and often struggled just to get dressed in the morning, he hardly ever missed a day of work. His determination and love are an inspiration to me every day.

When I'm unhappy with something, people know, because I don't want to hold on to it. I'd rather deal immediately with the stuff that bothers me, so using my network - my girlfriends, my husband, my mom - I talk a lot, I vent.

I like to talk about my obsession with french fries because I don't want people to think that 'Let's Move' is about complete, utter deprivation. It's about moderation and real-life changes and ideas that really work for families.

The one thing I believe is that families are off-limits. And I think my husband said it, and he was clear on that. And I totally agree with him.

Every girl, no matter where she lives, deserves the opportunity to develop the promise inside of her.
