Your body has a built-in janitorial crew—an internal system that clears out damaged cells, broken proteins, and toxic waste. It’s called autophagy, and it plays a key role in preventing disease, improving brain function, and extending your healthspan.

But here’s the problem: Most people never give this crew the signal to clock in.

In this episode of Healthspan Digest, host Aaron Shaw breaks down:

  • What autophagy is (and why it matters for your energy, immunity, and longevity)
  • How fasting and exercise both trigger this powerful process
  • The key differences between the two—and which is more effective
  • How to combine them for maximum benefit (without burning out)
  • A simple once-a-week protocol to kickstart your cellular cleanup crew
  • How to eat after to upgrade your recovery and resilience


🎯 The takeaway? You don’t need extreme fasts or brutal workouts. You need to signal your body the right way—and let the internal crew get to work.
