If you’re a woman in your 30s, 40s, or 50s feeling like your body is betraying you, this episode reveals the hormonal, gut, and environmental triggers behind perimenopause that most doctors never address, and exactly what you can do about it.
Host Dave Asprey sits down with Cynthia Thurlow, a nurse practitioner, CEO and founder of the Everyday Wellness Project, and a globally recognized expert in intermittent fasting and women’s hormonal health. Her TEDx talk on intermittent fasting has surpassed 10 million views, and she brings over 20 years of functional medicine clinical experience to one of the most underserved conversations in longevity and human performance.
Together, they tear apart the outdated medical narrative around perimenopause and menopause, exposing how a lack of knowledge, not biology, is destroying relationships, careers, and quality of life for millions of women. Dave and Cynthia dig into the gut microbiome’s role in every symptom women experience in midlife, the mold toxin that is 10,000 times more potent than human estrogen and directly linked to hormonal chaos, and why biohacking your hormones as early as 35 could be the most important longevity move a woman makes. They also cover why statins are wrecking women’s metabolism, how trauma accelerates ovarian aging and mitochondrial decline, the surprising connection between histamine reactions and hot flashes, and why GLP-1 micro-dosing alongside hormone replacement therapy is a game-changer for body composition and anti-aging.
This episode is essential for listening for anyone serious about biohacking, sleep optimization, functional medicine, longevity, brain optimization, supplements, metabolism, human performance, and smarter not harder approaches to women’s health.
