Sugar-free and low-sugar chocolate
Three different claims — sugar-free, no added sugar and reduced sugar — mean three different things, and none of them means calorie-free.
If you read nothing else
Sugar-free, no added sugar and reduced sugar are three different claims. None reduces the fat, and high-percentage dark chocolate gets to low sugar without any substitution.
Three claims, three meanings
Sugar-free means no sugars, and in the EU it is a regulated nutrition claim with a defined threshold. The sweetness comes from something else.
No added sugar means no sugar was added, which permits naturally occurring sugars — relevant where milk solids are present, because lactose is a sugar.
Reduced sugar is a comparative claim against a reference product and says nothing in absolute terms. A reduced-sugar milk chocolate can contain more sugar than an ordinary dark one.
None of the three is a claim about energy content. Fat is the dominant energy source in chocolate and it does not change.
What replaces the sugar
Usually a polyol — maltitol, erythritol, xylitol — sometimes with a high-intensity sweetener such as steviol glycosides. Polyols supply bulk as well as sweetness, which matters because sugar is a substantial share of a bar's mass and something has to occupy that space.
They behave differently. Maltitol is close to sugar in sweetness and body and is the most common; it is also the one most associated with digestive effects at quantity, which is why sugar-free confectionery frequently carries a laxative-effect statement. Erythritol is less sweet and gives a cooling sensation on the tongue. Steviol glycosides are intensely sweet and contribute no bulk, so they are used alongside something that does.
The simplest route
Higher-cocoa dark chocolate. A 90% bar contains very little sugar without any substitution at all, and it is an ordinary product rather than a specialist one.
That is not a recommendation about anyone's diet — it is a note that the sugar-free category exists mainly to deliver a sweet product, and a reader who simply wants less sugar has a straightforward option that does not involve polyols.
