CHICAGO - MAY 19: Low calorie packages of Kellogg's Special K Bars are displayed on May 19, 2006 in Chicago, Illinois. The latest weapon in the battle against weight-gain are 100-calorie snack foods and drinks offered by food makers like Nabisco, who in 2004 developed a line of products latching onto the number 100 that doctors and nutritionists approved for snacks. Nabisco, which is marketed under the Kraft Foods line, reformulated five varieties of its popular cookies and crackers to meet the 100-calorie limit. Other companies have followed Nabisco, which racked up $100 million in sales within a year of launching the line. (Photo by Scott Olson/Getty Images)
