Should You Get a DEXA Scan?

In today’s episode, we take a closer look at DEXA scans — what they measure, what the numbers actually mean, and whether getting one is worth it.

These scans are becoming more common in fitness and wellness settings, providing insight into body fat, muscle mass, visceral fat, bone density, and even something called “biological age.” But how should we interpret those numbers? What can they tell us about our health — and what can’t they tell us?

Using my own recent scan as a starting point, we explore how body composition data can serve as a baseline for understanding our bodies, tracking changes over time, and making more informed decisions about strength training, fat loss, and bone health.

In this episode, we talk about:

* The difference between total-body composition scans and clinical DEXA scans used to diagnose osteopenia or osteoporosis

* What body fat percentage actually measures — and why it’s different from BMI

* The concept of body recomposition: reducing body fat while maintaining or gaining muscle

* Why visceral fat matters for metabolic and cardiovascular health

* What biological age means — and why it should be interpreted cautiously

* How to understand T-scores in bone density reports

* Why the hip and spine are the gold-standard sites for diagnostic bone density scans
