What DEXA Actually Measures and Its Limits

In this episode, I’m joined by Dr Belinda Beck to challenge long-held beliefs about osteoporosis and bone health. We break down what actually works, what doesn’t, and why many people are being given outdated advice.

We explore the science of bone adaptation, the importance of heavy resistance training, and how to think about prevention and treatment across the lifespan.

What We Cover

• Why walking is not enough for bone health
• How heavy lifting changes bone strength
• What DEXA scans can and cannot tell you
• The impact of menopause on bone loss
• Exercise vs medication for osteoporosis
• Common myths and misleading advice

If you want to better understand how to build and protect your bones, this episode is a must-listen.

You can learn more about Dr Belinda Beck’s work via her website, follow updates on Facebook, or explore her clinical and training work at The Bone Clinic and ONERO.
