Many no-calorie drinks have calories through artificial sweeteners such as aspartame, but the amount of sweetener used (aspartame has the same amount of calories as sugar but is 200x sweeter) is so little that it is negligible, and considered to have zero calories. For things that don’t use sweetener, it’s just flavored water.
I couldn’t really find much on zero-calorie foods, but I’m assuming those would be foods that take more energy to digest than it would give.
