The Healthiest Bread in the World!

Hi, anyone tried making this bread. I would like to try making it by using Sourdough starter instead of yeast. But not sure how much to use and when.

Also, i intend to use Sunflower Flour 1:1 proportion instead of the almond flour. My understanding is that almonds takes alot of water to grow almonds, so i am hesitant to use it.
