“Healthy” Until the DEXA Said Otherwise. Why “Fine” Labwork Can Still Hide Heart Risk

In this episode of The Healthspan Podcast, Dr. Robert Todd Hurst, MD, FACC, FASE, sits down with Natasha Mortenson, a HealthspanMD member, for a real-world transformation story that challenges what most people believe about aging, muscle, and hidden risk. Natasha shares how a DEXA scan revealed opportunities she could not see on the surface, and how small, deliberate changes over time led to dramatic body composition improvements, including losing 12 pounds of fat while gaining two and a half pounds of muscle in eight months.

They also dig into what Natasha calls the iceberg syndrome, the hidden risk beneath “looking healthy,” the role of testing and re-testing, and why “one size fits all” advice breaks down in real biology.

About the Guest: Natasha Mortenson is a HealthspanMD member sharing her personal longevity and body composition journey, including how objective testing, personalized planning, and consistent strength-focused work helped her pursue exceptional results and reduce future health risks.
