Safety Profile

Contraindications & Risks

Eating disorders, underweight, pregnancy/nursing, type 1 diabetes, certain medications, electrolyte imbalances, refeeding syndrome (extended fasts)

Important Notes

Strong scientific backing - autophagy research (Nobel Prize 2016), Longo's longevity research, Fung's clinical success with diabetes. Ancient practice now clinically studied. Extended fasts (>5 days) need medical supervision. Refeeding syndrome is real risk. Counter-intuitive but powerful. Not starvation - therapeutic fasting with intention and safety.
