SERVICES

Three tests. The complete picture

Each one measures something your mirror, your scale, and your wearable cannot see.

DEXA body composition scan
1
DEXA Body Composition Scan

Know Your Body.

~8 minutes

Know exactly what to change — and whether it's working. Your fat, muscle, and bone mapped region by region, with precise, repeatable accuracy.

2
VO₂ Max & Endurance Test

Transform Your Fitness.

~15 minutes

See 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).

LongevityPerformance
VO2 Max treadmill test
RMR metabolism breath test

RMR Metabolism Test

Optimize Your Metabolism.

~15 minutes

Eat for your actual metabolism — not someone else's. Your precise resting calorie burn, measured by breath analysis. No more guessing with online calculators.

Who it's for

For every body. At every stage.

Your body knows things you don't. DexaFit Boston is how you finally listen.

Lose Weight

Stop guessing.
Start knowing.

Visceral Fat Risk
+55%
Elevated visceral fat is one of the strongest independent predictors of cardiovascular disease — and DEXA is one of the few tools outside a hospital that can estimate it.
Weight loss & GLP-1 users

You don't have a weight problem. You might have a composition problem.

Your scale can't tell you whether what you lost was fat or muscle. DexaFit can.
On GLP-1 medication? Studies show ~30% of weight lost may be lean mass. Know where you stand.
Smart scales carry error margins of 10% or more. DEXA is a gold standard for body composition.

Train with precision.
Measure with it too.

Lean Muscle Precision
±1%
DEXA regional lean-mass precision. No wearable or scale comes close.
Athletes, gym-goers & competitors

Because 'Good Enough' doesn't win. Measure the margin.

VO2 Max: the performance ceiling your wearable estimates. DexaFit measures it directly.
Regional lean mass by limb and trunk—the structural detail no wearable or scale can see.
RMR tells you what your body actually burns at rest. Fuel training with data, not calculators.

Women's Health

Your body is changing.
The data explains why.

Tracked in
8min
DEXA tracks how fat, lean mass, and bone shift through hormonal change—so you can see what's actually moving.
Perimenopause & hormonal change

The most important changes are the ones you can't see.

Menopause shifts fat distribution toward visceral stores—your scale can't see it, but DEXA can.
Bone density often declines around menopause. An 8-minute scan gives you a reading you can track over time.
Your metabolism changes in perimenopause. RMR testing shows exactly how much.

Bone Health

Strong bones aren't
visible in the mirror.

Baseline in
8min
A comfortable 8-minute scan gives you a bone-strength reading you can track over time.
Bone health & older adults

Bone strength is easy to overlook — and easy to measure.

1 in 2 women over 50 will experience an osteoporosis-related fracture (International Osteoporosis Foundation). Knowing where you stand is a first step.
8 minutes. Comfortable. A clear picture of where your bone strength stands today.
Staying strong as you age isn't luck. It's something you measure and track.
Bone density readings are a general wellness indicator only. They are not a diagnostic bone scan and do not diagnose osteopenia, osteoporosis, or any medical condition. For diagnostic bone testing or any concern, consult your physician.

VO2 Max Mortality Gap
A 5x difference in all-cause mortality between the least fit and most fit quintiles (Mandsager et al., JAMA 2018).
Longevity & healthspan

Wearables measure signals. We measure structure.

Elevated visceral fat is associated with significantly higher cardiovascular risk. Your BMI cannot see it. DEXA quantifies it in pounds.
VO₂ Max outpredicted smoking, diabetes, and hypertension as a mortality risk factor in a 122,007-person study (Mandsager et al., JAMA 2018).
Your old test is being compared against a growing dataset. Every retest sharpens the picture.

WHAT YOUR SCALE CAN'T SEE

Two people. Same weight. Opposite outcomes.

Both are 42. Both weigh 145 pounds. Both passed their last checkup.

Higher-Fitness Profile One carries 22% body fat, evenly distributed, with strong bone density and a VO₂ Max in the top quartile for her age. Her visceral fat is low.
Higher-Risk Profile The other carries 36% body fat, concentrated in her trunk. Her visceral fat load is 4.2 pounds—the kind of fat that surrounds the organs and is associated with higher cardiovascular risk. Her VO₂ Max is in the bottom quartile, and her bone density reading is lower.
The scale shows the same number. BMI puts them both in the "normal" range. Yet their body composition is very different. One profile reflects strong fitness markers; the other reflects higher-risk markers worth paying attention to. A single DEXA scan reveals the difference in body composition in about 8 minutes.

The scale says they're identical. BMI chart says 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.

QUICK ANSWERS

Common Questions

  • DexaFit uses the same DEXA, VO₂ Max, and RMR technology found in research settings 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 meaningful.

    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 estimates, you get a precise picture of your body composition, metabolism, and performance to inform your own goals

  • Same fix as the others — one phrase to change. Here's the cleaned version:

    "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 a gold standard for body composition measurement. Two people can weigh the same and look the same in the mirror but carry completely different 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 offers much higher precision—approximately ±1% for body fat percentage. It also maps composition by region—arms, legs, trunk—and estimates visceral fat, which consumer devices can't do.

  • VO₂ Max measures how efficiently your body uses oxygen under exertion—your cardiorespiratory ceiling. In a landmark study of 122,007 people, it was one of the strongest predictors 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 yours directly, rather than estimating it 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, so knowing your number gives you both 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 assesses it through breath analysis (indirect calorimetry), a well-established method for estimating resting metabolism. Online calculators and app estimates can differ meaningfully from a measured result, which can be the difference between a nutrition plan that works and one that doesn't

  • It takes the guesswork out of eating. Instead of relying on an algorithm's estimate, you'll have a measured starting point for your calorie needs—useful context for whatever goal you and your provider are working toward

  • 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 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.
