Episode notes
Fiber Acts As A Hormone And Metabolic Regulator
- Fiber is a metabolic and hormonal regulator beyond digestion.
- Cynthia Thurlow links declining estradiol in midlife to microbiome shifts, inflammation, and reduced short-chain fatty acid production that fiber helps correct.
Host's Personal Loss And Recovery Of Fiber Tolerance
- Cynthia Thurlow personally lost fiber tolerance after six weeks of antibiotics in 2019 and took 18–24 months to rebuild tolerance.
- She uses this experience to empathize with patients who currently can't tolerate much fiber.
Why Midlife Increases Need For Fiber
- Menopause-related hormone changes worsen insulin sensitivity, body composition, and gut motility.
- Thurlow explains estradiol loss increases visceral fat and progesterone changes slow smooth muscle contractility, making fiber more important in midlife.
