I am familiar with Mowll, I’ve listened to some of his summits. But his position that diabetes is not a disease is in direct conflict with current mainstream medical thinking. And using that as an argument that you can misuse words such as “reverse” just seems disingenuous. In medical terminology we don’t talk about reversing disease as meaning that the “symptoms” are reduced, we mean that the actual disease or defects are reduced. The term to use is “remission,” telling people that you can reverse or cure their diabetes is deceptive. That doesn’t stop people from using it as a marketing tool anyway. I wrote about the use of this term back in 2015.
ps. In terms of the more “reasonable” alternative medicine practitioners I give Mowll credit for at least recognizing and leveraging allopathic medicine.
