I have made the full version and half version of this recipe. They stay really moist, and are definitely high in fibre. I only use sugar in the recipe, as I don't use artificial sweeteners, This is just my personal choice. My muffins didn't appear as nice looking as the posted photo, as they were a little uneven on top, but they still tasted great. Next time, I might try to cut back a bit on the xanthan gum, as maybe my batter was a little too thick. I might also consider adding a little cinnamon.
