Well, he may have some points to make. And certainly sugar alcohols slow down a number of people. But so much of what he says sounds like a ploy to sell his (overpriced) book.

A few things he says sets my bells ringing. I wouldn't trust him 100%:

"I taught my readers that how MUCH one ate was far more important than WHAT TYPE of food one ate."

This did NOT hold true for me...in fact, everything Dr. Atkins says seems to be true for me, so I am wary at the thoughts about what he "got wrong." Maybe I'm just the right metabolic profile Dr. Atkins wrote about, and other people would be different, but I think this guy is a little off.
