The adhesive on a U.S. envelope contains around 1.7 calories per gram, according to Food and Drug Administration data, which amounts to one-tenth of a calorie per lick.

An average U.S. postage stamp contains approximately one-tenth of a calorie in its adhesive. This surprising fact addresses the common and quirky question: how many calories do you consume when you lick a postage stamp?
