I have lived it personally, but here is the scientific study and their way. I went 20 grams or less and they only require 30 or less. But I went to 5.8 instead of only 6.5 so outperformed their requirement for their study. I did not hear about Virta till I was already on my way to remission. Sarah Hallberg, who unfortunately passed away a couple years ago, was one of the early presentations I saw on the Low Carb Down Under Youtube channel. Then later listened to other doctors and researchers from Virta. Anyway, here is Nick Norwitz giving a presentation about the research.

I highly recommend the Low Carb Down Under series. I learned of most of the doctors and researchers I follow through that avenue.
