Sugar substitutes: erythritol and stevia

Erythritol is a sugar alcohol, with a taste closest to sugar and a slight cooling sensation in the mouth. Stevia is a plant extract, dozens of times sweeter than sugar, with a herbal aftertaste that not everyone likes.

Erythritol is more convenient for baking: it provides volume. You need only tiny amounts of stevia, and it is easy to overdo it — then bitterness appears.

Both can cause bloating in large amounts, more often erythritol.

Those that come in ready-made “fitness” products together with something else.

Store-bought bars, protein cookies, and “keto chocolate” usually contain not only a substitute, but also syrups, starches, and maltitol, which does raise blood sugar. You need to read the ingredients more carefully here than on regular products: the words “sugar-free” on the package guarantee nothing.

Honey, agave syrup, and coconut sugar are not substitutes at all — they are sugar under a different name.

Dark chocolate, 85% or higher, 10-20 g. This is a daily ceiling, not a target, but it settles the question of “wanting something at the end” without any special ingredients.

The second option is a small amount of berries. They fit within the 50-70 g allowance if you keep track of the amount.

The third is not a dessert at all, but a last meal of a normal size. An evening craving for sweets most often means that you did not eat enough during the day.

With irritable bowel syndrome, sugar alcohols, including erythritol, are often poorly tolerated and cause bloating and diarrhea.

With diabetes, switching from sweets to substitutes does not eliminate the need to monitor glucose and is not a reason to change treatment on your own. With eating disorders, any rituals around sweets are best discussed with a specialist.

Children and adolescents do not need substitutes without a specific reason.

It is also a sugar alcohol, but it behaves differently from the others: it noticeably raises blood sugar.

The problem is that maltitol is the most common sweetener in commercial “keto” and “diabetic” products: it is cheap and has a texture closest to sugar. A bar labeled “sugar-free” that contains maltitol may produce exactly the effect you bought it to avoid.

The second issue is tolerability. In amounts provided by one or two bars, it often causes bloating and diarrhea.

There is no strict limit in the method because the issue is not grams, but frequency.

Occasional use — a cup of coffee with stevia, a dessert for a celebration — changes nothing. A daily keto dessert in the evening does: it maintains the ritual of having something sweet at the end of the day.

The guideline is simple: if you cannot remember a day without a sweet taste during the past week, substitutes have stopped being a tool and have become a habit.

There is not enough direct evidence that substitutes themselves increase cravings, so this cannot be stated as a fact.

But there is a simpler reason for the method’s caution: something sweet at the end of the day is a learned sequence. While it is repeated, it remains in place. By changing the content of the ritual, you do not change the ritual itself.

That is why the recommendation is not a ban, but an order: the first month without a sweet taste, then as needed.
