They say ignorance is bliss, so it's often easier to indulge in an unhealthy snack or meal when you don't know exactly how much exercise you would need to do to burn it off. Sure, some of you might say, "I don't care. I deserve to indulge." But we know that some of you would be horrified to know that you'd need to walk for more than five hours to burn off a Ruby Tuesday's Turkey burger, which weighs in at 1,173 calories. Or how about the ultimate indulgence for some people -- McDonald's fries? If you knew you'd have to walk for almost two hours to burn off 350 calories from a medium serving, would you still belly up to the drive-thru?
