Why a 575-Pound Man Had Perfect Metabolic Labs – Craig Emmerich
In this episode of The Feldman Protocol, can individual biology shape whether a given diet or protocol actually works — or does one approach fit everyone? Craig Emmerich (co-author and nutrition researcher alongside Maria Emmerich) makes the case for bioindividuality in metabolic health, discussing his decade-long journey with chronic Lyme disease and ankylosing spondylitis, the protein-sparing modified fast as a weight-loss tool, a fat-cell–centric view of insulin resistance, oxidative priority of fuel sources, and whether AI may reshape personalized medicine. 📎 Mentioned in this episode: • 23:34 – Craig & Maria Emmerich — The Art of Metabolic Health (book): `https://www.amazon.com/Art-Metabolic-Health-METABOLIC-RESILIENCE/dp/B0GWWK9HLC` • 1:46:03 – Craig & Maria Emmerich — Carnivore Cookbook (book): `https://www.victorybelt.com/the-carnivore-cookbook` • 1:48:59 – Podcast episode: Craig Emmerich on Judy Cho's podcast: `https://podcasts.apple.com/us/podcast/nutrition-with-judy-carnivore-diet/id1529951307` • 2:32:25 – Maria Emmerich — ketomaria.com (books, blog, social media hub): `https://ketomaria.com/` 🔥 This episode is sponsored by us -- Own Your Labs 👉 `https://ownyourlabs.com/sp/` Private blood testing services 🩸Over 300 blood tests 💰Extremely affordable ❤️ We love our customers (Yes, we are literally funding the entire podcast from our own company -- so if you want to show your support, keep getting your private blood testing through our service.
