Normal Labs But Still Exhausted? The Mitochondrial Problem Doctors Miss

About This Episode

If you’re sleeping well, eating clean, exercising—and still exhausted—this may be an engine problem, not a fuel problem. This is Part 1 of my Mitochondrial Health Series, where I start with the foundation: mitophagy—your body’s ability to clear damaged mitochondria. In longevity medicine, I call this mitophagy failure: damaged mitochondria (“zombie batteries”) stop producing clean energy and leak signals that can trigger inflammation, brain fog, and that 2 p.m. crash. In this video, I break down: • Why zombie mitochondria can keep you stuck in “sickness behavior” • The key biology: PINK1 + Parkin (how your cells tag and remove broken mitochondria) • My 4-step energy protocol: 14–16 hr overnight fasting, Zone 2 cardio, heat (sauna/hot bath), and urolithin A + spermidine • The NAD+ trap: why NMN/NR can backfire if you “fuel” before you “clean” *Chapters:* 00:00 The "Zombie Battery" Cause of Fatigue 01:54 Why Your Cells Think They Are Dying 04:43 The Cleanup Crew: PINK1 & Parkin 07:02 Protocol 1: The "Janitor" Fast (AMPK vs. mTOR) 08:44 Protocol 2: Why HIIT Might Be Making You Tired 09:59 Protocol 3: Heat Shock Proteins & Sauna 11:30 Protocol 4: Supplements (Urolithin A, Spermidine) & The NAD+ Mistake 15:18 Summary: The 4-Step Energy Protocol ✨ Get 5 Easy Longevity Tips & Dr. Hillary Lin's Weekly Newsletter for Free: https://www.hillarylinmd.com/subscribe *About the Show:* The Longevity Show with Dr. Hillary Lin takes complex medical research and distills it into practical, easy-to-understand advice for living a longer, healthier life.
