One thing that gives me pause is that this all rides on the word of Dr. Stephens (and those participating). And Stephens doesn't strike me as a bad guy, but I do wonder if he is naive in some ways. I forget which video I saw of him where he essentially says "There is no possible way glucose can be harmful to you".
While I can appreciate that perhaps he has seen some incredibly positive results, that is a very bold claim. Especially considering some reports I've seen from the relatively small number of accounts I'm following in regards to this protocol. (The most pertinent example is someone on RPF who is experiencing intense dental pain basically immediately upon beginning this protocol.)
All of that is to say: if, in my limited purview, I am seeing that report (and others of less significant harm/setbacks), how can Stephens say there is no way it can be harmful?
