What Is Autophagy? Autophagy = your cell’s built-in recycling and repair system. It literally means “self-eating.” Your body breaks down old, damaged, misfolded, or dysfunctional proteins, organelles, and debris and recycles them into fresh building blocks. Think of autophagy as: ✔ cellular detox ✔ cellular recycling ✔ cellular rejuvenation When autophagy is high → cells stay young, energy improves, inflammation drops. When autophagy is low → damaged proteins accumulate → inflammation → aging → disease. 2. How Autophagy Works (Mechanisms in Simple Terms) Step 1 — Detection The cell senses stress, energy shortage, or damaged structures. This activates AMPK and inhibits mTOR — the ON switch for autophagy. Step 2 — Tagging Damaged proteins/organelles get tagged for removal. Step 3 — Autophagosome Formation A membrane “bubble” forms around the unwanted material. This bubble = an autophagosome. Step 4 — Fusion with Lysosome The autophagosome fuses with a lysosome — an organelle filled with digestive enzymes. Step 5 — Breakdown & Recycling The cell digests the material and recycles amino acids, fatty acids, and nutrients to build new cellular parts. What Stimulates Autophagy? (Ranked: Strongest → Weakest) 1. Prolonged Fasting (16–72 hours) The strongest activator because fasting drops insulin and activates AMPK massively. • 24–36 hours = big spike • 48–72 hours = maximal autophagy 2. Caloric Restriction / Time-Restricted Eating Eating in a shorter window (8 hours or less) reduces mTOR and increases autophagy. 3. High-Intensity Exercise / VO₂ Max Training Exercise creates energy stress → AMPK activation → autophagy. (Hormetic stress is a principle emphasized in longevity materials. 4. Ketosis / Low-Carb States Low insulin + high AMPK = autophagy upregulated. 5. Heat Stress (Saunas) Heat shock proteins stimulate protein cleanup pathways. 6. Cold Exposure Cold thermogenesis mildly increases autophagy by energy demand. 1. Neurodegenerative Disorders • Alzheimer’s • Parkinson’s • ALS Autophagy removes misfolded proteins (tau, beta-amyloid). 2. Metabolic Disorders • Type 2 diabetes • Insulin resistance • Fatty liver 3. Immune & Inflammatory Disorders • Chronic inflammation • Autoimmune flare reduction • Inflammaging (autophagy decline is a core driver) 4. Mitochondrial Dysfunction / Fatigue Autophagy clears damaged mitochondria (mitophagy), improving energy. 5. Cardiovascular Health Clears plaque-forming debris, reduces oxidative stress. 6. Cancer Prevention (Not treatment) Healthy autophagy prevents DNA damage and genomic instability. Supplements That Increase Autophagy 1. Spermidine • Dose: 1–2 mg/day • Form: Wheat germ extract or synthetic spermidine • Mechanism: Inhibits EP300, enhances autophagosome formation 2. Resveratrol • Dose: 150–500 mg/day • Form: Resveratrol or trans-resveratrol • Mechanism: Activates SIRT1 → increases autophagy and mitochondrial biogenesis. 3. Berberine (natural metformin analog) • Dose: 500 mg, 2–3x/day • Mechanism: AMPK activation → strong fasting mimic. 4. EGCG (Green Tea Extract) • Dose: 200–400 mg/day • Mechanism: AMPK activation, antioxidant, promotes proteostasis. 5. Curcumin • Dose: 500–1500 mg/day (with black pepper or liposomal form) • Mechanism: Induces autophagy through anti-inflammatory pathways. 6. Quercetin + Fisetin • Dose (quercetin): 500–1000 mg/day • Dose (fisetin): 100–500 mg/day (often used intermittently) • Mechanism: Senolytic → removes senescent cells and enhances autophagy. 7. NAD⁺ Precursors (NMN or NR) • Dose: 250–500 mg/day • Mechanism: Supports sirtuins → promotes autophagy + mitochondrial repair.
