Emily Deans (of the fab Evolutionary Psychiatry blog) on what to believe:
Forget the paleo myths. Forget the personalities. Are you eating (for the most part) real food (excepting autoimmune disease). Are you exercising? How is your sleep? What are you feeling? What are the pitfalls? What is your family doing?
Fix those issues and answer those questions first. Know where you are, and then look for more guidance. We are working on a network of doctors who might help. I hope cults of personality won’t get in the way, but don’t let it confuse you. What makes sense, from every angle? Never suspend disbelief.
