The practical way that you might help yourself to mindlessly eat less pizza? When you make or order your next pizza, have it cut into at least twice as many pieces (from 8 to 16) and ideally eat it from a plate placed on a large table. Do so, and if this study's findings hold true, you might consume nearly 50% less!
