Well, what Agent641 left out is that manufacturers in the US are allowed to “round down” to 0 if the calories/amount per serving are below a certain threshold. So by claiming 1,532 serving, they can get away with saying the calories in each serving are tiny and write 0. Tick-tack uses this to claim 0 calories even though the are mainly sugar, simply by claiming a portion is 1 tick-tack. It’s just another ridiculous US regulation no one wants to fix.
