We’ve been making small changes to the book since it was first published as we need to. I don’t believe we made any changes specifically because of what was written in that review, mostly because many Boyd’s original issues were factually incorrect, and the remaining issues, like the ingredients in some of the bars we recommend, are a difference of what we found in the research and what he feels is unhealthy. If we were shown research that whey protein isolate, for instance, was detrimental to a person’s health, we’d change our recommendations. There is no evidence of this, however, so we’ll keep recommending it.

We’d be much more likely to make changes based on a review like the one from Stephan Guyenet over at Whole Health Source, who rebutted some of our recommendations with evidence. His review and the private discussions that followed made Jeff and I take a good look at the research to make sure what we had recommended was valid.

We’ll most likely put out a second edition at some point (I know, a lot of hedging going on there), but we haven’t seen enough evidence to make large changes to our recommendations at this point.
