The Transformative Power of Fasting and Difficult Conversations

Jeff Krasno’s personal health transformation—reversing diabetes, shedding 60 pounds, and reclaiming his health at age 50—is a masterclass in what he calls “good stress.” In this episode, we dive into the simple but powerful idea that discomfort might just be the medicine we all need. Jeff, the founder of Commune and host of the Commune podcast, shares how fasting, cold exposure, resistance training, and attention to modern habits helped him regain his energy, build muscle, and thrive.

Together, we discuss how metabolic dysfunction has become the norm, how adaptive stress responses can be harnessed to reverse chronic illness, and why building muscle is not only the antidote to obesity but also a critical factor in longevity. If you’re interested in reclaiming your vitality and learning how to work with—not against—your biology, this episode will speak to you.

We cover:

• Jeff’s story of personal health transformation at midlife
• What “good stress” is and how to harness it to improve health
• Why chronic ease leads to chronic disease
• Cold therapy, fasting, and training as adaptive stressors
• The importance of resistance training for blood sugar control
• How metabolic dysfunction hides in plain sight
• Practical tips to increase non-exercise activity thermogenesis (NEAT)
• Building muscle as the path to longevity and disease prevention
