There are legal definitions for the phrase "low calorie". Companies must obey that definition if they make packaging that implys low calorie.
The legal definition: 50 g of that product must have fewer than 40 cal.
Since a stick of gum is ~2g, and has ~5 cal, then 50 g of that gum would have ~125 cal. It is therefore about triple the amount of calories legally allowed to imply it is low calorie.
