My current hunch is that Ray Peat never had any problems with keeping VA in balance because his metabolism has always been super fast (he said he ate 10,000 calories as a young man while working a very chill job), so he simply never had to deal with a toxic buildup of it and therefore wouldn't know what to do about it. On the other hand, Grant and Dr. Smith had a much different history and have had to deal with chronic VA toxicity, so they figured out how to deal with it. That doesn't mean they know everything else there is to know about health and how different people react to different things. It's probably not so much that one camp is right and the other is wrong, but these people came from vastly different backgrounds. In such a case it's reasonable to expect that you can learn something useful from both. The question is how to properly combine the lessons learned from both sources?
