Let me know what you think if you try it. I do have xantham gum, but haven't tried it yet. Maybe I'll put some in my next batch to see how it changes it!

The nutritional yeast is for added nutrition and fat.
I bought Bobs Red Mill Large Flake Nutritional Yeast and 1 tbsp is:
24 calories, 10g fat, 3.2g protein, with just 0.8 net carbs.

I searched for foods to use that were low in carbs, but higher in nutrition. I figured if you are going to eat bread, it should be worthwhile nutritionally to your diet!
