Gizmo, what makes you think that coconut flour is not low carb? If I can eat it, without a spike, trust me, it IS! It's not carb-free, but it does not bother my BG. Most recipews use it in smaller volumes than wheat flour, too.
(Meanwhile I have not seen yeast-leavened recipes with it, either. Most of those use gluten flour).
