Good question. Most of his books contain the same core material. He's probably not changing his tune. much, though will include any new breakthroughs in science he finds relevant. Maybe a new case study or two. I would love to see a book of just case histories.

If we have the older edition of the book, should we still get the new one?
Hi, the new book contains much more information, and virtually all the chapters have been updated/revised. Dr. Phil

The cynic in me thinks that this is, of course, just what he would say. Still, at 364 pages it seems the new edition MUST have a good bit of new information. Get it now or wait for the combined "Training & Eating for Endurance" later this year? Decisions, decisions.....
