DEXA vs. Old-School Body Tests: Why the Right Tools Matter

Let’s be real—your body isn’t a math problem. So why do most health tests treat it like one?

You’ve probably heard of BMI, skin calipers, smart scales, or even the Bod Pod. They all try to guess what your body’s made of. But guessing is the key word here.

If you want real answers—about your fat, muscle, and bone strength—you need a better tool. That’s where DEXA scanscome in.

Let’s break it down, no science degree needed.

The Old-School Stuff (And Where It Fails)

Here’s a quick look at the tools most people still use—and why they might be holding you back:

🧮 BMI (Body Mass Index)

This one’s simple: it just divides your weight by your height.

Why it’s used: Fast, cheap, and easy.
Why it falls short: It can’t tell fat from muscle. So if you're fit or muscular, it might label you as “overweight.” Yikes.

✂️ Skinfold Calipers

Pinch your fat in a few spots and do some math.

Why people like it: Portable and cheap.
Why it’s a problem: Human error. Plus, it only measures fat under the skin—not the deep stuff that really matters.

⚡ Smart Scales & BIA Devices

These send a tiny electrical current through your body and try to guess what’s fat vs. muscle.

Why it sounds cool: It’s tech!
But: Your hydration, what you ate, or even where you place your feet can change the results. It's not reliable.

💦 Hydrostatic Weighing & Bod Pod

Water or air is used to guess your body fat.

Pretty accurate... in theory. But you have to undress, fast, and breathe just right. Not ideal for everyday life.

The Truth: These Methods Are Just... Estimates.

They can’t see what’s inside.
They can’t tell you where your fat is.
They definitely can’t track muscle or bone changes over time.

That’s where DEXA wins. Every time.

What Makes DEXA So Different?

DEXA stands for Dual-Energy X-ray Absorptiometry. Yeah, it sounds fancy. But all you need to know is this:

🔍 It sees everything—fat, muscle, and bones.
📍 It shows where things are in your body (hello, belly fat).
📊 It tracks your changes with crazy-high accuracy.

Here’s what DEXA gives you that old-school tests can’t:

✅ Real Accuracy

Not an estimate. A direct readout of your fat, muscle, and bone.

✅ Visceral Fat Data

This is the dangerous fat around your organs. DEXA sees it. Calipers and smart scales can’t.

✅ Muscle Tracking

Want to know if you're building muscle or losing it? DEXA tells you what’s really going on.

✅ Bone Density

Yes, DEXA checks your bones too. That means you can watch out for things like osteoporosis.

⚠️ Quick PSA About “DEXA Vans”

Some places offer mobile DEXA scans in vans. Sounds convenient, right? But here’s the issue:

🛻 Vans move. DEXA machines need to stay perfectly still and level. If they’re not, the scans aren’t accurate—and that means your results can’t be trusted.

DexaFit uses certified, in-clinic machines that are locked in place. No movement. No wonky numbers. Just clean, reliable data.
