Instead of displaying calories on menus, experts say people may make healthier choices if menus list how much exercise is necessary to burn off calories.
In a new study, researchers gave study participants different menus, some with calories listed, and some that showed how much brisk walking one would have to do to burn those calories.
The 300 participants, all under age 30, ordered and ate less when they were shown the exercise it would take to recover from such a meal.
By law, chain restaurants must display calorie content on menu boards.
This study is from researchers at Texas Christian University and is scheduled for presentation at Experimental Biology 2013 in Boston.
