Let’s Move!— an anti-obesity initiative spearheaded by first lady Michelle Obama — is, literally, on the move to celebrate its third anniversary. A star-studded cast is pitching in to battle the childhood obesity epidemic.

This week, Obama is scheduled for a tour in Chicago and Mississippi to highlight progress and future goals of the initiative, including:

  • a trip to elementary schools in Clinton, Miss., with daytime TV host Rachael Ray. In Mississippi, nutritional standards in schools have helped childhood obesity decline by more than 13 percent since 2005.
  • an examination of a Walmart store in Springfield, Miss., which according to a White House release, focuses on changes implemented by the corporation to make healthier food more accessible and affordable.
  • an announcement in Chicago that will “bring physical activity back to schools.” Obama will be joined by athletes including including Dominique Dawes, Bo Jackson, Colin Kaepernick and Serena Williams, along with NIKE CEO Mark Parker and Secretary of Education Arne Duncan.

Obama has also promoted the initiative on “Late Night with Jimmy Fallon,” authored public service announcements with “Sesame Street” icon Big Bird, and is scheduled to discuss the campaign on “Good Morning America” and “The Dr. Oz Show” this week. She’ll hit social media next week with a Google+ hangout March 4 and a Twitter chat March 6.

Let’s Move! was announced on Feb. 9, 2010, in light of statistics showing that childhood obesity rates in the U.S. have tripled over the last three decades. Visit Let’s Move! online for milestones and collaborations since its inception.
