Let’s say you like to run, and you run at 2 mph, your food intake would be converted not into calories, but how much running you would have to do to burn that food off.
Drink a soda, and the 140 calories are displayed in your selected unit. Soda (140 cal) = 4 miles running at your average speed. People would get a very quick idea as to how much their choice of foods relates to their behavior.
