Executives from a number of food companies said they would reduce the calorie count in their products....and it seems they meant it.

A study by the Robert Wood Johnson Foundation has found the companies, which include General Mills, Kellogg, Campbell Soup and Kraft, set their guidelines in 2010 to be effective in 2015.  They've cut the equivalent of 78 calories per person per day.  That is four times the 1.5 trillion calories that they had pledged to cut by next year.

Other companies included in the pledge were ConAgra Foods, Coca-Cola, PepsiCo and Hershey.  78 calories, by the way, is about the equivalent of an average cookie or a medium-sized apple.
