Paleo: A Complete Step-By-Step Beginners Guide This book gives a step-by-step guide on how to follow the "Paleo" Diet. This lifestyle that is gaining popularity is based on the theory that humans have not biologically adapted to eat grains, dairy, or processed foods. This guide breaks down and explains what to eat, what not to eat, and why, as well as how to prepare mentally for these changes, how to avoid pitfalls, and tips for exercise. In addition, it gives recipes and resources to someone who is new to the Paleo Diet and does not have a background in medicine or nutrition so that they can get started.
