I found the following blog post fascinating. It's a long read, but well worth it. I will be ending my high-fat diet soon, I think (just have to get more settled to be able to get non-jetlagged, "standardized", blood tests), and might try radically low-fat for a few weeks, then retest. In defense of low fat: a call for some evolution of thought (part 1)
I'd be interested to hear people's thoughts on Minger's post.
Search the Society archives - (when they're up...) - for "Pritikin" for some background.
