I had hoped to have had a civil discourse, but this is difficult when the questions come from uncivil people. I also don’t have time to answer superficial questions of others like ‘what is the detailed mechanism of protein induction of high cholesterol levels’ – that easily could become an entire but relatively useless dissertation when the “mechanism” most decidedly is a symphony of mechanisms, as I explained in our book. At this point, the far more important observation is the dramatic increase in serum cholesterol.
Hmmm, I wonder what Campbell's definition of "uncivil" is? Seems to have some conceptual overlap with the second sentence, i.e. those who ask "superficial" questions are being "uncivil". The question in question came from me, and I'm glad to see it had one of the desired effect. My preferred outcome would have been that Dr. Campbell actually answered the question. Then I would have learned something. It is unfortunate that he instead evaded the question as above, because then all we learn is that a) he doesn't have an answer, but b) thinks he does, and is thrown into painful cognitive dissonance when confronted by the truth of his ignorance. The nonsense about there being a "symphony of mechanisms" is, I believe, a subtle trick played on Dr. Campbell by his own mind. There are indeed many possible causes, and may be several interacting processes. But he confuses "I don't know which of the many possibilities contributes to the effect" with "here is what we know, a complex process". Classic mental band-aid for cognitive dissonance.
Anyway, I think my goal has been accomplished. I wanted to know if Dr. Campbell had any relevant information. If not, I wanted him to publicly torpedo his own credibility. Mission accomplished. Next time he wants to show up and bash a low-carb or paleo book an Amazon, you have ample material to demonstrate his irrationality.
