What actually happens when you don’t eat for three full days?
In this fascinating episode, I have a great discussion with NY Times bestselling author, Ben Azadi, to unpack the science — and surprising benefits — of a 72-hour fast. From resetting your dopamine and sharpening focus to burning visceral fat and regenerating cells, this conversation reveals why fasting may be the most powerful healing tool available.

How Fasting Heals the Body and Brain
Dr. Jockers explains how fasting triggers autophagy — your body’s built-in repair system — to destroy old, damaged cells and create new, stress-resilient ones.
You’ll also learn how ketones fuel your brain, reducing inflammation and enhancing creativity, while growth hormone surges to preserve lean tissue and accelerate fat burning.
The Spiritual and Emotional Reset
Beyond the physical benefits, fasting resets more than just metabolism. It recalibrates dopamine levels, deepens clarity, and strengthens discipline. Whether your goal is healing, longevity, or personal growth, this episode offers a rare look at how fasting can transform the body, brain, and spirit.
