Your Mitochondria Are Eating You Alive (How to Rebuild Them) | Oct 27, 2026

Inside every one of your cells live tiny ancient bacteria called mitochondria. When they fail, and they fail decades before you feel sick, they drive cancer, Alzheimer's, heart disease and diabetes. Here's how they fail, and how to rebuild them without drugs. **Chapters** 00:00 Introduction 00:33 What mitochondria actually are 02:01 The four ways mitochondria fail 03:56 The diseases this explains 05:34 How to rebuild your mitochondria 07:35 The bottom line **Key takeaways** Mitochondria decide whether a cell lives or dies, control inflammation, sense nutrients and regulate hormones. They fail in four ways: oxidative damage, DNA mutations, dysfunction, and failed cleanup (mitophagy). Broken mitochondria release DNA fragments that trigger the cGAS-STING pathway and chronic low-grade inflammation. What rebuilds them: Zone 2 cardio, high-intensity intervals, time-restricted eating, cold and heat, good sleep, and avoiding what poisons them. **Study** Seyfried TN et al.
