72-Hour Fast Reflection
Show Notes: erickheam.com/090
In this episode of the Rise Above Chaos podcast, Erick reflects on a recent 72-hour fast and how the experience reshaped the way he thinks about health, longevity, and the body's natural ability to heal. This was not about weight loss. It wasn't a detox. And it wasn't about proving toughness. It was about giving the body something it rarely gets in modern life—time and space to repair itself. Erick walks through the physiological and mental shifts that occurred over the three days, from the initial transition away from sugar dependence to deep cellular repair driven by autophagy and metabolic flexibility. Along the way, he shares both the subjective experience and the objective data that confirmed what was happening beneath the surface. This episode reframes fasting as a strategic tool for healthspan, resilience, and long-term performance—when done intentionally and sustainably.
In this episode, you'll discover:- Why a 72-hour fast is not about deprivation, but about activating the body's repair mechanisms
- What happens during the first 24 hours as the body burns through glycogen and shifts fuel systems
- How insulin reduction opens the door to fat metabolism and ketone production
- Why hunger comes in waves—and what that reveals about modern eating patterns
- What changes during hours 24–48 when fat adaptation and mental clarity increase
- How autophagy acts as the body's cellular cleanup system and why it matters for aging
- What makes the 48–72 hour window a unique longevity zone few people experience
- How fasting activates hormesis, a beneficial stress response
- Why ketones act as signaling molecules, not just fuel
- Measurable health improvements including lower resting heart rate, higher HRV, and better sleep
- Why longevity is built through repair, not constant growth
- How fasting improves metabolic flexibility
- What made this approach sustainable with monthly 36-hour fasts
"My 72-hour fast wasn't about deprivation—it was about giving my body time to remember how to heal."
"You don't build longevity by doing more all the time. Sometimes, you build it by doing less—and letting biology do its work."
