Isabella Cooper – Part 1 – The Chemical Removed From Tampons Is Still in Most Diapers

In this episode of The Feldman Protocol, what does beta-hydroxybutyrate between meals actually reveal about a person's insulin state — and why might that matter for understanding chronic disease risk? Dave sits down with Isabella Cooper (PhD), a biochemistry and pathophysiology scientist whose research spans assay quality control, hyperinsulinemia detection, ketone thresholds, mitochondrial function, and the lipid energy model, making the case that personalized insulin thresholds — not population-wide cutoffs — may be key to identifying subclinical metabolic dysfunction.🔥 This episode is sponsored by us --Own Your Labs 👉 `https://ownyourlabs.com/sp/48` Private blood testing services🩸Over 300 blood tests💰Extremely affordable❤️ We love our customers(Yes, we are literally funding the entire podcast from our own company -- so if you want to show your support, keep getting your private blood testing through our service.
