Episode 168

Published September 1, 2026

In this episode, Phoebe Liebling joins host Dr. Jaclyn Smeaton to discuss bone loss, mixed messaging in fitness and nutrition culture that can damage bone density, and the critical role of estrogen in bone remodeling.

Their conversation also covers:

  • The invisible and non-linear nature of bone loss
  • Estrogen as a stimulant for osteoblast activity and calcium retention
  • Common habits like chronic underfueling, excess cardio, and fasted training and how they can quietly contribute to bone loss
  • How typical DXA scans begin at 65, missing the fastest bone-loss window which occurs much earlier during perimenopause
  • A practical framework for reversing bone loss through nutrient-dense eating, protein intake, and targeted supplementation
