This story from U. S. News and World Report says:

• Parents pick lower calorie foods for their kids when calories are posted on fast food menus, says a study.
• The average calorie savings is around 100 calories less for each meal, which is significant say the lead researcher of the study.
• The parents did not choose items with fewer calories for themselves.
• The study simulated families eating out at a fast food restaurant—not in the real ones.
• The study is published in the online issue of the journal of Pediatrics, January 25.
• A separate paper, presented at the 2009 annual meeting of the Obesity Society, found the same trend.
