Four leading female health experts — exercise physiologist Dr. Stacy Sims, fertility doctor Dr. Natalie Crawford, OB-GYN Dr. Mary Claire Haver, and orthopedic surgeon Dr. Vonda Wright — join The Diary of a CEO for one of the most comprehensive conversations about women's health ever recorded.
The discussion reveals shocking systemic gaps: less than 1% of $450 billion in US research funding goes to women over 40, despite women being 51% of the population. Women weren't required in clinical studies until 1993. Women live 6 years longer than men but spend 20% more of their lives with chronic disease or mental health disorders. Every cell in an XX body expresses genes differently from XY — down to satellite cells that behave differently in lab conditions.
The experts explain the menstrual cycle as a whole-body health marker, not just a fertility signal. FSH drives egg growth in the follicular phase (estrogen-dominant), then after ovulation the luteal phase brings progesterone — raising core temperature, resting heart rate, appetite, and shifting how the body uses fuel. An irregular cycle is a major red flag for systemic problems.
PCOS affects at least 10% of women and is driven by insulin resistance, not ovarian dysfunction. The experts stress that lifestyle interventions — whole foods, fiber, sleep, stress reduction, and building skeletal muscle — are the most effective tools for managing PCOS, combating insulin resistance, and improving hormonal health. They warn against fasting and undereating, which worsen cortisol, disrupt circadian rhythm, and lead to muscle loss.
The conversation covers endometriosis (7-10 year average diagnosis delay, impacts the whole body), menopause (severely under-taught in medical school, estrogen receptors exist throughout the entire body), and the historical dismissal of women's health complaints — from the 'whiny woman' label to hysteria diagnoses that led to institutionalization.
Key Takeaways
- Less than 1% of US research funding goes to women over 40 — women weren't required in studies until 1993
- Your menstrual cycle is a whole-body health marker — an irregular cycle is a red flag for systemic problems
- PCOS is driven by insulin resistance, not ovarian dysfunction — building muscle is one of the best interventions
- Fasting and undereating backfire for women: they raise cortisol, disrupt hormones, and increase cravings
- Estrogen receptors exist throughout the entire body — brain, bones, muscle, gut, blood vessels — not just reproductive organs
