Which sounds worse: eating something that will take running two miles to work off, or eating something that is about 200 calories?

They are actually the same thing.

Scientists are under the impression that many Americans are ignoring the calories on the side of packaging, but would respond differently if exercise data were in its place, reports Daily Mail.

This is why some scientists are calling for packaging to replace calories with exercise in efforts to make people eat healthier.

"They [scientists] say that if a menu tells you a double cheeseburger will take a 5.6-mile hike before the calories are burned off, most people would rather choose a smaller hamburger which would require a walk of 2.6 miles," reports Daily Mail.

A group of researchers from Johns Hopkins Bloomberg School of Public Health in Baltimore studied local teenagers and found that if they gave them exercise data about soda they were more likely to grab a healthier drink or a smaller bottle.

The findings were published in the American Journal of Public Health.
