I wanted to create this short video on sugar alcohols to answer the question, “should you subtract sugar alcohol sweeteners as your net carbs?”

Normally you would take the total carbs on the back of the label and minus the fiber as well as the sugar alcohols. In theory, sugar alcohols don’t get absorbed in the small intestine or raise the blood sugars. The thought is because they don’t act just like sugar, we can deduct sugar alcohols to get the net carbs.

However, I disagree with this. Out of all of the sugar alcohols, there is only one that is zero on the glycemic index, which is erythritol. If you have erythritol as your sugar alcohol on keto, definitely subtract it from your total carbs to get your net carbs. But, sugar alcohols like xylitol, maltitol, and sorbitol produce a reaction on the glycemic index. It’s not high, and it’s less than table sugar and glucose, but it’s not zero.

I would not recommend deducting sugar alcohols like xylitol, maltitol, and sorbitol in your calculations. But, again, you can deduct erythritol.

If you’re consuming stevia or monk fruit, you don’t have to worry about these. They have such a small amount of calories, and you do not have to factor them into the equation at all because they don’t spike insulin.
