Trillions of Calories Getting the Ax to Cut Down on Childhood Obesity

Several of the nation's largest food companies say they'll take 1 1/2 trillion calories out of their products by 2015 to reduce childhood obesity. First lady Michelle Obama announced the move today after a coalition of food manufacturers pledged to cut calories as part of an agreement with a group of concerned nonprofits. Mrs. Obama earlier this year launched her own anti-obesity campaign.

To keep the companies accountable, the Robert Wood Johnson Foundation, a philanthropic and research organization that works to improve the nation's health, will evaluate how the groups' efforts affect the number of calories kids consume.
