Chronic disease doesn’t feel “modern” when you’re living it, but the causes often are. We take on the Paleodeficit Syndrome, the idea that your body still runs on an ancestral operating system while your environment has been rewritten in a few generations. That mismatch helps explain why obesity, insulin resistance, prediabetes, type 2 diabetes, fatty liver, and cardiovascular risk keep rising even as nutrition advice gets louder and more confusing.
We dig into the biggest dietary shifts that separate ancestral eating from the modern diet: grain dependence after agriculture, acellular carbohydrates from refined flour, ultra processed foods, industrial seed oils and omega 6 excess, and the way fortification can hide a low nutrient diet inside “enriched” staples. We also explore why potassium, iron, and zinc bioavailability matter, why fermentable fiber and the gut microbiome are central to metabolic health, and why seasonality used to shape human physiology in ways we rarely consider now.
Then we bring receipts. We discuss a short clinical Paleo diet intervention where insulin resistance markers (HOMA IR) and triglycerides improved fast, and we push past the simplistic cholesterol narrative by focusing on LDL particle quality: small dense versus large buoyant LDL and how insulin levels influence both. Along the way, the agouti mouse research makes the case for nutritional epigenetics, showing how diet can change gene expression and even affect future generations.
If you want practical ancestral health takeaways without hand waving, this one will challenge you in the best way.
