Hormone-synchronized 28-day cyclical fasting for female metabolic resilience

A 28-day cyclical fasting strategy mapping three distinct metabolic phases: The Power Phase (Days 1-10: deep fasting and low carbs for estrogen production and autophagy), The Manifestation Phase (Days 11-15: moderate fasting and cruciferous vegetables to clear surplus estrogen during ovulation), and The Nurture Phase (Days 16-28: zero fasting and clean complex carbohydrates to supply progesterone synthesis). Primary Citation: Fast Like a Girl: A Woman's Guide to Using the Healing Power of Fasting to Burn Fat, Boost Energy, and Balance Hormones (2022). Verified Public Record: "Women cannot fast like men. During the late luteal phase before menstruation, the body requires adequate glucose to synthesize progesterone; extending fasts during this window spikes cortisol and disrupts the cycle." — Fast Like a Girl (Chapter 5: The Fasting Cycle Calendar, p. 104 (2022))
