Gary Brecka guides Day 2 of a 72-hour water fast with a specific protocol: three liters of spring water with mineral salt, Perfect Aminos, and H2 tablets. He explains how the body depletes glycogen and enters ketosis, triggering autophagy and growth hormone release. Taylor Dukes covers female cycle timing for fasting and its use in cancer and metabolic care.
