On Monday, in a direct answer to Michelle Obama's announced combat regarding childhood obesity, a coalition of key food makers promised to bring in new, more healthy choices, trim portion sizes and trim down calories in present products.

The Healthy Weight Commitment Foundation, an alliance comprising Campbell Soup, Coca-Cola, General Mills, Kellogg, Kraft Foods and PepsiCo, will cut down 1 trillion calories by the conclusion of 2012 and 1.5 trillion calories by the end of 2015.

The 16 associates make up 20-25% of food used in the United States.

Obama said at a news convention at the Eisenhower Executive Office Building, "This is precisely the kind of real private-sector commitment that we need. And I hope that more will follow the example that they've set".

The declaration is one of the first significant outcomes of the First Lady's "Let's Move!" campaign that intends to put a stop to childhood obesity within an age group.

The industry's vow arrives two months after Obama asked food companies "to move farther, faster" and less than a week after the White House declared the results of its Childhood Obesity Task Force.

The industry has been stressed from Mrs. Obama and from State and Local Governments contemplating junk-food taxes and other anti-obesity steps.
