Daily micro-protocols for the 90-day miracle window

🔬 Pre-Bump Biology
Better sleep lowers cortisol and inflammation; steadier insulin raises SHBG and tames excess androgens. That combo supports the KISS1→GnRH→LH/FSH rhythm, guards egg mitochondria, and reduces sperm oxidative stress. Tonight we pair a pre-sleep breathing reset with a daytime 16:8 eating window to stack wins for ovulation, semen quality, and implantation.
🧬 Protocol Drop
Today’s Allopathic Protocol:
Adopt 16:8 time-restricted eating for the next 12 weeks: first meal ~12:00, last bite by 20:00, ≥1.2–1.6 g/kg/day protein, training and supplements inside the window. If you have PCOS or irregular cycles, shift earlier (e.g., 10:00–18:00) to maximize SHBG and insulin benefits.
Today’s Holistic Protocol:
10 minutes of nasal diaphragmatic breathing within 30 minutes before lights-out: ~6 breaths/min (4 s inhale / 6 s exhale), exhale longer than inhale, eyes closed, lying or semi-reclined. Do this nightly for 8–12 weeks to improve sleep quality and calm HPA-axis stress.

📚 Glossary Pop
Sex Hormone–Binding Globulin (SHBG): A liver-made protein that binds testosterone and estradiol. Higher SHBG means less free (active) androgen, which helps restore ovulation in PCOS and supports a healthier endocrine environment for conception.
