(CBS) Let's Move! - the Obama administration's campaign to fight childhood obesity - celebrated its second birthday and according to Tom Vilsack, Secretary of the U.S. Department of Agriculture, the campaign is doing what it's supposed to do. 

"For the first time in a long time, we did not see a rise in obesity rates," Vilsack told HealthPop. 

The campaign kicked off two years ago in the hopes of raising a future generation of American children who eat healthier and exercise more than their predecessors. "The physical and emotional health of an entire generation, and the economic health and security of our nation is at stake," First Lady Michelle Obama said at the program's launch on February 9, 2010.

Current estimates suggest 17 percent of American children and teens are overweight and obese - that's triple the rate of a generation ago, according to the CDC.

Since Let's Move! has sprung into action, several new measures to combat those rates have been launched, including the unveiling of the MyPlate icon that replaced the pyramid, as well as the Healthy, Hunger-Free Kids Act that President Barack Obama signed into law in December 2010, which led to healthier school lunch standards for the 32 million schoolchildren who participate in the National School 

Lunch and Breakfast programs.
