Episode Description from the Publisher

In this episode, Dr. David Jockers breaks down what happens inside your body during a 30-hour fast, including fat burning, ketone production, gut health improvements, and the cellular repair processes activated during fasting.   You'll learn how fasting impacts insulin levels, supports a healthier gut microbiome, reduces inflammation, and helps your body shift into a state of regeneration and renewal.   Discover the connection between fasting, growth hormone, brain health, longevity, and how to maximize the benefits of a longer fasting window safely and effectively.
