One in three American children is overweight or obese，putting them at higher risk of developing diabetes，high blood pressure，high cholesterol（胆固醇） and other illnesses．Billions of dollars are spent every year treating obesity-related conditions．"None of us wants this future for our kids．We have to act，so let's move．"Mrs．Obama said at the White House．
Being the First Lady and a mother of two，Mrs．Obama has launched her campaign against childhood obesity in the US，hoping to encourage people to live healthier lives．
She admitted that she herself was not immune to the temptations of junk food．"I love burgers，fries，ice cream and cake．And so do most kids，"she stated，"We're not talking about a lifestyle that dismisses all that．The question is how we help people balance that out so that they're not facing life-threatening，preventable illnesses．Instead，they're enjoying their food，they're eating their vegetables，they're doing their running and walking and playing and still have time to get a good，fun meal in every once in a while．"
The campaign contains four parts：helping parents make better food choices，serving healthier food in school vending machines and lunch lines，making healthy food more available and affordable，and encouraging children to exercise more．
The ambitious campaign，which Mrs．Obama hopes will be seen as her legacy（遗产），is intended to solve the childhood obesity problem in a generation，so that children born today can reach adulthood at a healthy weight．"This isn't like a disease where we're still waiting for the cure to be discovered．We know the cure for this．"she said．
