Stem Cell Fasting

Fasting triggers stem cell regeneration of damaged, old immune system. Water fasting triggers stem cell regeneration by forcing the body into a nutrient-deprived state that activates autophagy (cellular recycling) and kills old, damaged immune cells. This process lowers IGF-1 and PKA enzymes, switching stem cells from a dormant state to a self-renewal, regenerative mode to rebuild the immune and tissue systems.

Key Mechanisms for Stem Cell Regeneration:
Autophagy & Recycling: During prolonged fasts, the body breaks down old, inefficient white blood cells and cellular components, creating raw materials for new cells.

Metabolic Shift to Ketosis: After glucose stores are depleted (approx. 72 hours), the body burns fat for fuel, which activates intestinal and other stem cells to repair tissue.

Immune System Reboot: Studies show that 3-day water fasts can clear out damaged immune cells, prompting stem cells to generate entirely new, healthy immune cells upon refeeding.

Mechanisms: Stem cells repair tissue by differentiating into specialized cells (e.g., muscle, nerve) and by releasing bioactive molecules (exosomes/growth factors) that stimulate the body’s own repair systems.
