## Resource

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.
