Show Notes & Resources

We’re welcoming Cynthia in this episode to explore how women’s health shifts in midlife and why the gut may be the missing piece to massively better health. We hear why she emphasizes “digestive rest” over aggressive fasting, especially for women who struggle to build muscle or meet protein needs. She explains how perimenopause alters the microbiome, how the “microgenderome” evolves across puberty, pregnancy, and menopause, and why hormone replacement therapy can reshape the gut in meaningful ways. We also dig into hidden gut disruptors like alcohol, ultra-processed foods, antibiotics, and unresolved stress, along with the gut-brain connection, brain fog, and mitochondrial health. Cynthia challenges us to rethink restriction, prioritize muscle and sleep, and finally factor the gut into every hormone discussion.
