You got a DXA scan and walked out with a sheet full of numbers… and zero context.
In this episode, I break down what DXA actually measures, why it beats BMI for real body composition tracking, and how to interpret the metrics that matter for performance + longevity—especially FFMI (Fat-Free Mass Index) and ALMI (Appendicular Lean Mass Index).
We’ll cover:
DXA vs BMI (why BMI misses muscle, bone, and fat distribution)
What DXA measures: lean mass, fat mass, bone mineral content
FFMI and ALMI: what they are, why they matter, and how to use them
Why visceral fat trend is a bigger health signal than scale weight
The big upgrade: why longitudinal DXA (tracking change over time) beats a single snapshot
How researchers have used raw DXA imaging + clinical data + function tests to improve long-term risk prediction (the future of body comp + health forecasting)
Practical takeaway: DXA is not for flexing. It’s for baselines and deltas.
If you want a real signal-based plan: measure, reassess, and let trends—not vibes—drive your next move.
Drop DXA in the comments if you’ve had a scan, or DXADELTA if you’re scheduling scan #2.
