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.

We learned about dignity and decency - that how hard you work matters more than how much you make... that helping others means more than just getting ahead yourself.

Since we started the Let's Move! initiative, I've been looking for as many ways as possible to help families and kids lead healthier lives.

Much of what we do with our kids is social and that's good, and we shouldn't stop all that. I mean, how boring would it be that, no, we can't eat anything out so we're just going to go home and sit in the closet and wait to the next day.

I come here today as a Christian, a person of faith who believes we've all been called to serve our fellow men and women and to honor God's creation. We want our girls to know right from wrong, to always tell the truth, to treat people no matter who they are with dignity and respect, no matter how different they may seem...because we want our girls to know we are all God's children and there's so much more that unites than divides us.

We have had with Barack Obama some just amazing experiences traveling abroad, being able to introduce our children to the world.... I'm also humbled by the response and the receptiveness, not just here in America, but around the world. There's a part of that warmth and enthusiasm and hope that is surprising and humbling.
