Yes, allulose is keto-friendly
Your body doesn't use it for energy, so it doesn't count toward net carbs.
The full answer
Allulose is a rare sugar that your body absorbs but doesn't use for energy. About 70% is passed in urine unchanged, which is why it contributes almost no calories (0.2–0.4 per gram, versus 4 for sugar).
Studies show it doesn't raise blood sugar or insulin, and it won't knock you out of ketosis. Most keto trackers count it as zero net carbs.
In 2019 the FDA allowed companies to exclude allulose from "total sugars" and "added sugars" on Nutrition Facts labels, though it still appears under total carbohydrates. That's why some keto products look higher in carbs than they really are.
It browns and caramelizes like sugar, which makes it popular for keto baking. Large servings (over about 30 g at once) can cause bloating.
