Although the gains against childhood obesity are encouraging, the JAMA study was not all good news. Obesity rates in women over 60 rose significantly. Other obesity rates (children and adults) remained the same: 1/3 of Americans are still overweight and 1/3 are obese.

In 2010, First Lady Michelle Obama, wife of President Barack Obama, began a national program called "Let's Move!" to solve the problem of childhood obesity within a generation. Mrs. Obama has worked tirelessly for the cause of fighting childhood obesity. To learn more about Let's Move!, visit www.letsmove.gov.
