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.

I hate fund-raising. Haaaaate it. Hate, hate it.

Like so many American families, our families weren't asking for much. They didn't begrudge anyone else's success or care that others had much more than they did, in fact, they admired it.

Hope and change are hard-fought things.

And Barack and I were raised with so many of the same values, like you work hard for what you want in life. That your word is your bond; that you do what you say you're going to do. That you treat people with dignity and respect, even if you don't know them and even if you don't agree with them.

We have to make sure that our kids still feel good about themselves no matter what their weight, no matter how they feel. We need to make sure that our kids know that we love them no matter who they are, what they look like, what they're eating.

My happiness is measured against my kids' happiness - when they're in a good place, I feel really good.
