EP008 "Anything Meds Can Do, You Can Do Better" Part 7 of 12 - Brain Insulin Resistance

Hungry right after eating? Foggy no matter how much you sleep? It's not willpower — it's your brain. In Part 7 of our "Anything Meds Can Do, You Can Do Better" series, Richie and Amber unpack brain insulin resistance, one of Dr. Ralph DeFronzo's "Dirty Dozen" core defects of type 2 diabetes. Discover why your brain doesn't need insulin for fuel — but needs it for signaling — and how a broken hunger-satiety loop drives cravings, brain fog, and even Alzheimer's-like changes. The good news: it's reversible.

KEY TAKEAWAYS

🧠 Your brain uses insulin-independent glucose transporters (GLUT1/3) — fuel gets in fine, even with insulin resistance elsewhere.
🍽️ Brain insulin resistance breaks satiety signaling, causing nonstop hunger and cravings, even after eating.
💭 It's biology, not willpower — disrupted dopamine pathways make healthy habits harder to sustain.
⚠️ Chronic brain inflammation is linked to cortical thinning and Alzheimer's risk — but lifestyle changes can reverse it.
