In this episode, Dr. David Jockers shares what happened when he went 48 hours without food and breaks down the incredible changes your body experiences during a fast. You'll learn how fasting shifts your metabolism, lowers insulin, and activates fat-burning and ketone production.

 

Discover how extended fasting supports your brain, boosting clarity, balancing neurotransmitters, and increasing BDNF to enhance focus, creativity, and strategic thinking.

 

Explore the deeper benefits of fasting on your gut and cellular health, including autophagy, stem cell regeneration, and growth hormone release, which promote anti-aging, gut repair, and overall resilience.
