Presto!

This book is a must-listen: if you're going to read it, you should hear it from the horse's (or 1/3 of a cow dressed as an elephant) own mouth by listening to the audiobook. Penn does such an incredible job of reading his own writing.

As someone always interested in nutrition but with a personal bias towards eating all whole foods (not just plants), this book was a great way to challenge what I think I know about healthy eating.

What I appreciated most was Penn's transparency when discussing concepts that aren't supported by science (most of what he did), and that this book is simply a record of his experience without attempting to suggest a particular dietary approach for anyone else.

That said, the whole reading is irreverent, hilarious, and entertaining.
