Books can be tedious, especially diet and health books. I'm more of a fan of doing than reading. I've learned a lot more about myself just through general logging of my food and thoughts than most books but that said, I don't know everything, right!?
I have a general set of guides to refer back to and learn from when I get down or I need ideas. More importantly, if I'm in a plateau or have been off track and could use the reminders, I have them on hand without much effort. This set changes depending on my life stage so you'll see it morph over time but here is my current set and the amazon/affiliate link:
Eight Weeks to Optimal Health:
Dr. Andrew Weil
This was my first "bible" into the world of health and fitness. I still refer back to it often and I get inspired by his weekly tasks of buying flowers and experiencing forgiveness
Eat To Live/Eat For Health: Dr. Joel Fuhrman: His "prescription" of intense greens changed my husband's health. They have this really neat MANDI scoring guide, a quick guide to help you understand foods and their nutrient content at a glance. The link goes to a special PEERtrainer discount.
Women's Bodies, Women's Wisdom:
Dr. Christiane Northrup
I read this years before she went on Oprah and I experienced my early 30's in a much different way than many of my friends just based on her writings. Highly recommend this specific book
The 7 Habits of Highly Successful People
Stephen R. Covey
This book dives into discipline which I believe is the cornerstone of health and fitness. I'm not especially passionate about his writing style but the content is a must read.
This health and diet lifestyle mags is the one that I most relate to - it isn't about how to get the body to get a guy or nicely posed pictures of fitness routines. The editorial perspective is a bit more focused on health and diet information
