Pure ad hominem FUD. “This guy sometimes disagrees with scientists employed by the government, don’t listen to him!”.

The technical details are beyond my understanding but I’ve heard from a PhD in the field that Masterjohn’s understanding of metabolism is second to none. Whether his protocols work or not is certainly a case by case matter (like any health protocol), but he always appears to substantiate it with well-cited lines of argument, and is willing to engage with interlocutors.

As for spending years with changing protocols without getting anywhere besides spending lots of money, well that can be said for people with complex issues who go the institutionally approved route as well. It isn’t discrediting in its own right that a protocol didn’t work for some.
