The content was 5 stars, but I wished some ideas had been elaborated on, or clarified better, so I’m giving 4 stars. Definitely am glad to have attended a lecture Dr. Champ gave in Florida a few years back. Everything he said affirmed what I was thinking about diet, and hearing his research-backed opinions was so affirming for me. Definitely recommend checking out this book for the ideas set forth. I’m quite sure he is on to something!
