an (incomplete) list of the resources I've found most powerful and informative.
Nutrition & Physical Degeneration: read for free online. (nerd alert! it's dense, and probably not a good place to start for most people!)
a side note: I don't generally subscribe or advocate for the Price Foundation's philosophy on topics outside of nutrition.
Listen to Susan Pierce Thompson, PhD, talk about the neuroscience of food addiction & her own journey.
E.C. Synkowski on the 800 gram challenge: a simple, elegant way to up your nutrition.

an interview about the 800 gram challenge
Listen to family physician Dr. Gabrielle Lyon talk about her book, Forever Strong, and her style of medicine, "muscle-centric medicine". She'll teach you why she believes (and her research supports!) that skeletal muscle is the most important organ system in your body.

Dr. Casey Means' book about metabolic health and its impact on your quality and number of years lived is easy to understand, and radical in its acknowledgement of how your simple daily habits can predict the course of health or sickness. You can learn tons on her website, podcast, and from reading her book.
