US First Lady Michelle Obama has launched a nationwide campaign to tackle child obesity.
One in three children in the US is overweight or obese and Mrs Obama says the issue threatens America s future.
She is setting out an ambitious plan to try to solve the childhood obesity problem within a generation.
The Let s Move campaign will seek to raise the nutritional level of school meals and improve access to healthier food in deprived areas.
Mrs Obama has stressed that the campaign, launched on Tuesday, is not entirely hers.
She has enlisted the help of politicians, entertainers and sports personalities to get the message across
