The Physics of Why FASTING Repairs More Than You’ve Been Told

The Physics of Why FASTING Repairs More Than You’ve Been Told #feynman #humanbody #scienceexplained Your body is constantly repairing itself—but only when the right biological signals are switched on. Fasting is far more than skipping meals. It changes how your cells produce energy, recycle damaged components, and decide what gets rebuilt. In this video, you'll discover the hidden biology behind fasting and why it influences far more than metabolism. Learn how your body shifts from glucose to fat as its primary fuel, why autophagy removes worn-out cellular machinery, how mitophagy restores healthier mitochondria, and what happens when longevity pathways like AMPK, mTOR, and FOXO begin working together. You'll also see why fasting can increase BDNF, helping the brain adapt, learn, and function more efficiently. Whether you're curious about what is really happening inside your body, interested in what science actually says about fasting and healthy aging, or looking for explanations that truly make sense, this video will change how you understand one of the body's most powerful repair systems. 📚 SOURCES & FURTHER READING De Bold et al. – "Atrial Natriuretic Factor" Queen's University (1981) Weiss & Blaivas – Nocturnal Polyuria definition – Journal of Urology (2000) Vaughn et al. – Compression Stockings and Nocturia in Older Adults Richard Feynman – "The Character of Physical Law" (1965) Starling, Ernest – Capillary Fluid Exchange and Hydrostatic Pressure (1896) #richardfeynman #physics #humanbody #yourbody #scienceexplained
