This is why in the EU and other places the amount of calories, carbs and sugars, proteins, salt, fat and saturated fat, and fibre **MUST** be reported per 100g. And the net weight must also be present.
They may also give these values per “serving”, but only alongside the 100g values.
I was eating some chocolate today that listed the serving size as 3 squares of chocolate. The bar is made in rows of 4 squares…
But the bar was 85g (and yes I ate the whole thing).
I thought something similar had recently been brought in in the US too, residually in light of stuff like Tic Tacs have “zero” Calories per services despite being almost 100% sugar. Please tell me I didn’t imagine that ruling from several months ago…
As a diabetic who lives by counting carbs, I’m pretty sure you can’t have 0 calories but have carbs. If something is 0 calorie, I know that I can eat/drink it without needing insulin. No idea of the science, but basically carbs provide calories, or calories provide carbs.
And sweeteners contain extremely few carbs – it’s why diabetics use them, rather than sugar.
I know this doesn’t answer the question, but I felt it was an important thing to point out, in the interests of full education. Kinda.
This also has to do with a conversion “glitch” and the United States’ relative reluctance to adopt the metric system. In US food labels, there’s a technical distinction between little-c calories and big-C Calories. What we see in FDA nutritional labels are big-C Calories, which are technically **Kilo**calories. Since the US is always weird about the metric system, they decided to just avoid that Kilo altogether and make it even more confusing.
So, combine that with fast-and-loose rounding and you get 0 big-C Calories =< 999 little-c calories.
>What is the difference between calories and kilocalories?
> The “calorie” we refer to in food is actually kilocalorie. One (1) kilocalorie is the same as one (1) Calorie (upper case C). A kilocalorie is the amount of heat required to raise the temperature of 1 kilogram of water one degree Celsius.

You have two things going on here.
1. The label can round down. So if there are 0.499 Calories in a serving it can list 0. Bonus: Serving sizes for a lot of items are arbitrary so they adjust the serving size to hit the 0 Calorie rounding sweet spot
2. Artificial sweeteners are in there in very small amounts. I forget the numbers but an easy way to explain it is that the artificial sweeteners are thousands of times sweeter than regular sugar, so you only need very tiny amounts to make something very sweet.
Obviously number two has a lot of nuances and complicated things going on, but that doesn’t belong on ELI5.
