After holding the groundwork for nearly a year, Michelle Obama initiates a campaign on Tuesday against childhood obesity that she hopes will alter the way millions of Americans eat, exercise, look and feel.

"It's an ambitious goal, but we don't have time to wait", the First Lady said in an interview with USA TODAY in her spacious office in the East Wing of the White House. "We've got to stop citing statistics and wringing our hands and feeling guilty, and get going on this issue".

She reveals his shock after she learnt the about the alarming figures issued by the Centers for Disease Control and Prevention that the US possess 32% of children and adolescents today — 25 million kids — are obese or overweight.

The multifaceted campaign will proceed in a similar way as many government efforts do: with the appointment of a federal task force that will give government agencies 90 days to figure out what they plan to do to help.

Obama will target the busy parents who hit the fast-food drive-thru rather than home cook a balanced food and schools where cafeteria meals are fetched from vending machines and a la carte lines stocked with soda and candy bars.

Also, food companies that invest billions in fatty snacks to children are revealed to be the targets.
