How Much Walking to Burn Off That Burger?
If you knew it would take two hours of brisk walking to burn off the calories in that quarter-pound double cheeseburger, would you be less likely to order it? A Texas Christian University study reports that menus with such “exercise labels” led to fewer calories being ordered and consumed than either menus with calorie counts or ordinary menus. The test randomly assigned one of three otherwise identical menus to a group of 300 diners, ages 18-30. Those told how much brisk walking would be required to work off each item ordered food containing 15% fewer calories and ate 13% fewer. Calorie labeling, increasingly popular on menus, failed to similarly reduce consumption compared to menus with no calorie information at all. The findings were presented at the Experimental Biology 2013 meeting in Boston.
