How Much Exercise to Burn Off a Burger?

Menus displaying the amount of exercise required to burn off calories in a meal had some impact on food choice, researchers found. Individuals given menus with the exercise information not only ordered food with fewer calories compared with those given menus without such information (763 versus 902 kcal, P=0.002), they also consumed fewer calories (673 versus 770, P=0.01), according to Ashlei James, a graduate student at Texas Christian University in Fort Worth, Texas, and colleagues.
However, there was no difference in calories ordered (P=0.15) and consumed (P=0.19) between those whose menus had exercise information and those whose menus contained calorie counts, James reported at the Experimental Biology 2013 meeting in Boston.
