Michelle Obama Marking Three Years of 'Let's Move!'

First lady Michelle Obama is going on a national tour next week to celebrate the third anniversary of her "Let's Move!" program against childhood obesity.

Obama will also travel to New York City this week to talk about the third anniversary of "Let’s Move!" on Late Night with Jimmy Fallon, Good Morning America and The Dr. Oz Show, according to the White House.

"Thanks to these efforts, families now have access to more information to make healthier decisions for their children. Young people now have more opportunities for physical activity in their communities. Food in schools has been dramatically improved. More Americans now have access to healthy, affordable food closer to home. And the national childhood obesity rate has leveled off, and even declined in some cities and states," the administration said in announcing the tour.

Next Wednesday, Obama and Rachel Ray will be in Clinton, Miss., to laud new school lunch regulations with "more fruits, vegetables, low-fat or fat-free milk varieties, and whole grains; less saturated fat, trans fat, and sodium; and proper portion size."

On Feb. 28 in Chicago, Obama Secretary of Education Arne Duncan, Chicago Mayor Rahm Emanuel, NIKE, Inc. President & CEO Mark Parker, Dominique Dawes, Gabby Douglas, Allyson Felix, Bob Harper, Bo Jackson, Colin Kaepernick, Sarah Reinertsen, Paul Rodriguez, Serena Williams, and "a surprise musical guest" at an event.

The first lady will then go poke around a Wal-Mart in Springfield, Mo., "to see changes Walmart has made to reduce sodium and added sugars from packaged food items, to make healthier food more affordable, and to include a simple front-of-package seal for identifying healthier food choices."

Obama will follow up the stops with a Google+ hangout on March 4 and answering Twitter questions via her @FLOTUS account on March 6.
