Study Notes

  • Autophagy is a natural process that helps maintain the body
  • Autophagy removes damaged or non-functional components from cells
  • It also recycles other parts for cellular repair.
  • Functions as a method for the body to cleanse damaged cells
  • It also creates newer, healthier cells
  • "Auto" means self, and "phagy" means eating
  • The phrase literally translates to "self-eating".
  • Autophagy is a self-defense mechanism
  • Acts as a comprehensive recycling and cleaning process
  • Similar to pressing the reset button for the body
  • Bolsters survival
  • Helps adapt in response to various stressors and accumulated toxins in cells

Benefits

  • Anti-aging properties by reversing the body's clock
  • Creates younger cells
  • Autophagy increases to protect the body and improve longevity when cells are stressed
  • Maintained body function during starvation by breaking down cellular components
  • These components are then reused for essential processes
  • Allows the body additional time to obtain alimentation.
  • Removes toxic proteins from cells
  • Contributes to neurodegenerative disorders, such as Parkinson's and Alzheimer's
  • Recycles remaining proteins
  • Provides energy and essential building blocks for cells to use for repair
  • Stimulates the regeneration of healthy cells
  • Plays a role in cancer prevention

Diets that can boost autophagy

  • Intermittent fasting and ketogenic diets are among the best diets that stimulate autophagy
  • Fasting is the most effective method
  • The ketogenic diet which consists of high fats and diminished carbohydrates
  • These diets offer the same benefits as fasting without the need for actual fasting
  • Acts like a shortcut to stimulate the same beneficial metabolic changes
  • Glucose levels decrease with both intermittent fasting and the ketogenic diet
  • These diets involve decreased insulin and elevated glucagon
  • Glucagon level drives autophagy
  • Lower sugar levels triggers beneficial stress
  • This awakens and stimulates survival and repair mechanisms
  • Exercise plays a role in stimulating autophagy
  • Physical activity may stimulate autophagy in the organs that are part of metabolic regulation processes

Description

Autophagy is a natural process where cells remove damaged parts and recycle others for repair. This self-eating mechanism cleanses cells, promotes survival, and helps the body adapt to stress. It plays a role in anti-aging, removing toxic proteins, and maintaining function during starvation.
