What if the number on the scale is the least important thing about your health? In this conversation, Brigid sits down with Dr. Robin Berzin, founder and CEO of Parsley Health, to talk about what actually predicts women’s longevity: muscle mass, bone density, blood sugar balance, and root-cause healing. They dive into DEXA scans, functional medicine, hormone health, gut health, and how to eat for longevity in a real-life way—especially if you’re juggling kids, a career, and chronic inflammation or pre-diabetes symptoms.

If you’ve ever been told “your labs are normal” while you still feel exhausted, inflamed, or anxious, this episode will completely change how you think about women’s health.
