"Physical activity calorie equivalent labeling" is the academic way to describe food labels that calculate the calorie count of different foods by telling you how much exercise you'd have to do to burn it off.  For instance:  a small bar of chocolate containing about 230 calories would require 23 minutes of running or 46 minutes of walking to work it off.  There's new research suggesting these labels might be especially effective at promoting healthier eating.
