The stuff I did read by him a while back when it was free was pretty much like this guest article here:

I think his quote of his blog being a "a sanctuary for low-carbers in metabolic rehab" pretty much sums up everything I've read in the past from him, that carbs are not evil (the non-processed kind that is).
I also quoted some of his stuff in this article as well:

Outside of that, I honestly don't know what else he talks about in his membership site and ebooks.
