The Zcarb bars are made with Erythritol which is very different from the other sugar alcohols. From what I've read, erythritol is absorbed very quickly but isn't metabolized. Most of it passes through unchanged in your pee. Because it doesn't make it to the large intestine, there are no digestive issues and because it doesn't metabolize, it has a miniscule glycemic/caloric/ketogenic impact. |
