What Happens if You Fast for 100 Hours (Hour by Hour Breakdown!)

Author: Dr. Jockers January 8, 2026 Duration: 24:03

In this episode, Dr. David Jockers breaks down the powerful effects of fasting for 100 hours, including immune system reset and fat-burning benefits. Learn how your body taps into stored body fat, including visceral fat around your organs, and the remarkable regeneration process that happens as a result.

 

Discover how fasting activates stem cells, particularly in slower-healing areas like joints and cartilage, and how this process can improve muscle and joint function. Dr. Jockers also explains how extended fasting can lead to a dopamine reset, enhancing your sensitivity to rewards and reducing cravings.

 

Find out how autophagy, or "self-eating," ramps up as you fast, breaking down old, damaged proteins and cells to promote longevity. You'll also gain insights into the benefits of fasting for brain health, with ketones fueling mental clarity and reducing brain inflammation.
