Does it help to know that a double quarter-pounder with cheese delivers 740 calories? Probably not, a new study suggests.
Starting next May, fast-food chains with more than 20 locations in the United States must display calorie counts on menus. But this study questions whether the well-intended regulations will actually steer customers to less-fattening foods.
Research in Philadelphia, where such rules already exist, indicate as few as 8 percent of fast-food eaters make healthy choices based on menu calorie counts, the study found.
