The problem of childhood obesity has gotten a national platform in recent years, through first lady Michelle Obama's "Let's Move" campaign. Obama has even appeared with Elmo and Big Bird on Sesame Street to talk about nutrition and exercise.
Today, with the release of new obesity numbers, Obama suggests that her preschool audience has taken her advice to heart.
While obesity rates for most Americans haven't changed significantly over the past decade, among kids ages 2 to 5 the obesity rate dropped from 14% in 2003-2004 to just over 8% in 2011-2012, according to a report out Tuesday from the Centers for Disease Control and Prevention. That represents a drop of 43%, CDC said.
