Question: how many carbs in xylitol?
Answer: It's as sweet as sugar but contains just 3 calories per gram and 4 grams of carbs per teaspoon (4 grams) ( 4 ). Yet, like other sugar alcohols, the carbs in xylitol don't count as net carbs, as they don't raise blood sugar or insulin levels to the extent sugar does ( 15 , 16 ).
