Paleo, Ancestral and "alternative health" resources I have used:
Book: The Primal Blueprint
Author: Mark Sisson
The book is wide-ranging, easy to read, one of the best all around resources. The site is a great clearinghouse for up-to-the minute Paleo lifestyle community tips and concerns. See also Mark's work on ketogenic dieting, The Keto Reset Diet
Book: The Whole 30
Authors: Melissa & Dallas Hartwig
Outstanding, simple and direct intro to the Paleo diet. Wisely leaves the science to a companion book (It Starts With Food), making it easy for newbies to grasp basics and jump in with confidence. Me included.
Book: The Wahls Protocol
Author: Dr. Terry Wahls, MD
Dr. Wahl's own story of how she beat MS using Paleo and ketogenic dietary principles--and the implications for overcoming many other autoimmune diseases--is easy to read and too important (and well researched) to ignore.
Book: The Paleo Solution
Author: Robb Wolf
Engaging intro to Paleo, with emphasis on science and fitness. Robb's background as a biochemist really shines through. Robb is a breath of fresh air online too, offering tons of info in podcast format.
Book: Nourishing Traditions
Author: Sally Fallon
Sally is not a Paleo advocate per se, but offers so much clear, comprehensive nutritional advice in Nourishing Traditions that I could not put it down. Please read all the snippets, quotes and sidebars. Anyone thinking about processed food vs. whole foods needs this book--which also highlights the groundbreaking research of Weston A. Price (How the modern Western diet affects the health of ancestral/hunter-gatherer populations.)
Book: Paleo Principles
Author: Sarah Ballantyne Ph.D
Dr. Ballantyne, a medical biophysicist, has also written The Paleo Approach (and others) but I discovered her through this book. If you need the "fine print" on why Paleo works, this is your read--dense, encyclopedic, research- and citation-based. Includes an awesome list of actual studies that validate Paleo.
Book: Practical Paleo
Author: Diane Sanfilippo
Diane's overview of her journey to Paleo is passionate and compelling. I also appreciated her willingness to give helpful lists and repeat basic important principles throughout the text. A great Paleo starter book.
Book: The Paleo Cure
Author: Chris Kresser
Chris is an important Paleo and alternative health community figure as well as a functional medicine practitioner. His personal journey is very inspiring. I strongly recommend signing up for his super informative email updates.
Book: The Paleo Diet
Author: Loren Cordain, Ph.D.
I read this book and also Dr. Cordain's The Paleo Diet for Athletes. Dr. Cordain is considered one of the earliest pioneers of mainstreaming Paleo. His work is refreshingly direct, without being overly "scholarly." No hype here, just loads of well-researched guidance. Might be considered the "strictest" approach to Paleo, which is not a bad thing.
Book: Primal Fat Burner
Author: Nora Gedgaudas
I really enjoyed Nora's own story (the wolves!) and her passionate, well-argued approach to a well-balanced-keto dietary approach. She deeply influenced my extended keto phase, and had the most useful, hands-on advice to give about achieving and sustaining healthy ketosis.
