Increasingly, researchers are showing there’s a better way than just calorie postings to encourage eaters to make healthier decisions: by informing consumers how much exercise it would take to burn a meal off.

A study by researchers at UNC’s medical school, published in the journal Appetite, showed the kind of choices people make when randomly presented with different types of menus with differing levels of nutritional information: one with no nutritional info, one with calorie info, one with calories plus the minutes of walking required to burn the calories, and a fourth with calories plus the distance required to burn off the calories.

“People who viewed the menu without nutritional information ordered a meal totaling 1,020 calories, on average, significantly more than the average 826 calories ordered by those who viewed menus that included information about walking-distance,” writes Scientific American.
