If a product is below like 15 calories per serving, it can be labeled as 0 calories. Coffee is famous for having zero calories when it’s actually 5-10 calories a serving.

Tic Tacs infamously list a single mint as the serving size, so despite being little sugar pills, they’re printed as 0 calories.
