SERVICES
Four tests. The complete picture
Each one measures something your mirror, your scale, and your wearable cannot see.
Know Your Body.
~8 minutesKnow exactly what to change—and whether it's working. Your fat, muscle, and bone mapped region by region, with clinical-grade precision.
Transform Your Fitness.
~15 minutesSee how many healthy years you're building—and how to build more. The single strongest predictor of longevity ever studied (Mandsager et al., JAMA 2018).
Optimize Your Metabolism.
~15 minutesEat for your actual metabolism—not someone else's. Your precise resting calorie burn, measured by breath analysis. No more guessing with online calculators.
Balance Your Hormones.
Quick ResultsThe inside story your body can't tell you by feel. Comprehensive blood panels that surface what routine checkups often miss.
Who it's for
For every body. At every stage.
Your body knows things you don't. DexaFit Boston is how you finally listen.
Stop guessing.
Start knowing.
You don't have a weight problem. You might have a composition problem.
Train with precision.
Measure with it too.
Because 'Good Enough' doesn't win. Measure the margin.
Your body is changing.
The data explains why.
The most important changes are the ones you can't see.
Strong bones aren't
visible in the mirror.
Your bone loss is silent — until it isn't.
Your feedback loop starts here.
Wearables measure signals. We measure structure.
You don't need a goal.
You need a baseline.
8 minutes gives you a complete picture of your body.
WHAT YOUR SCALE CAN'T SEE
Two people. Same weight. Opposite outcomes.
Both are 42. Both weigh 145 pounds. Both passed their last checkup.
On a scale, they're identical. On a BMI chart, they're both "normal." To their doctors, they look the same.
One is building healthy years. The other is losing them—and no one has told her.
A single DEXA scan would have shown the difference in 8 minutes.
WHAT YOU LEARN
Stop guessing. Start knowing.
Most people live in their body for decades without ever truly understanding it. That changes here
Your body has been trying
to tell you something.

QUICK ANSWERS
Common Questions
-
DexaFit uses clinical-grade instruments—the same DEXA, VO₂ Max, and RMR technology used in research hospitals and published studies. Your results are compared against age- and sex-matched reference data from a dataset spanning 4 continents and over a decade of real-world scans. That context is what turns a number into something you can act on.
Our testing is combined with our proprietary software that turns your results into clear, personalized insights and detailed reports you can actually use. Instead of generic advice, you receive precise guidance for improving body composition, metabolism, and performance.
-
DEXA maps your body composition region by region—fat mass, lean mass, bone mineral density, and visceral fat—using dual-energy X-ray absorptiometry. It's the clinical gold standard for body composition measurement. Two people can weigh the same and look the same in the mirror but carry completely different risk profiles. DEXA shows the difference. 8 minutes. Your complete structural picture.
-
Smart scales and bioimpedance devices estimate body fat using electrical signals, with error margins that can exceed 10% compared to DEXA. DEXA measures directly, with approximately ±1% precision for body fat percentage. It also maps composition by region—arms, legs, trunk—and quantifies visceral fat, which no consumer device can do.
-
VO₂ Max measures how efficiently your body uses oxygen under exertion—your cardiorespiratory ceiling. A landmark study of 122,007 people found it to be the strongest predictor of all-cause mortality ever measured, outperforming smoking, blood pressure, and cholesterol as risk factors (Mandsager et al., JAMA 2018). Most people have never had it tested. DexaFit measures it directly, not estimated from a wearable algorithm.
-
Anyone who trains, anyone who wants to live longer, and anyone curious about where they actually stand. VO₂ Max is trainable at any age. Knowing your number gives you a target—and a way to measure whether your training is working.
-
RMR stands for Resting Metabolic Rate—the number of calories your body burns at rest just to keep you alive. DexaFit measures it through breath analysis (indirect calorimetry), which is the clinical standard. Online calculators and app estimates can differ from your actual number by 20–30%, which is often the difference between a nutrition plan that works and one that doesn't.
-
It removes guesswork from eating. You'll know exactly how many calories your body needs for fat loss, muscle gain, or maintenance—based on your measured metabolism, not an algorithm's guess about it.
-
Book online, choose the tests you want (DEXA, VO₂ Max, RMR, or a combination), and visit the center. Your results are analyzed and explained in a detailed report, with your data compared against age- and sex-matched reference ranges from our clinical dataset. Information you can bring to your trainer, your nutritionist, or your doctor.
Your body has a story. Now you know how to read it.
