DEXA Body Composition Scan
A DEXA scan measures your body fat, lean muscle and visceral fat, region by region, in about 10 minutes. No referral, results in your Mito dashboard.
- Body fat, lean muscle and visceral fat, broken down by arm, leg and trunk
- About 10 minutes on an open table, with no needles and a tiny radiation dose
- No referral needed. Your report lands in your Mito dashboard, next to your labs
- HSA/FSA eligible
- Results on your Mito dashboard
Scanned at 350+ partner centers nationwide
Why people order the DEXA Body Composition Scan
-
See whether you're losing fat or muscle
The scale only shows total weight. DEXA separates fat from lean mass, so you can tell whether a diet, a training block or a weight-loss medication is taking muscle with it.
-
Protect muscle on a GLP-1
In body composition substudies of the semaglutide and tirzepatide trials, roughly a quarter to two fifths of the weight lost was lean mass. A baseline scan and a follow-up show how much of yours is muscle.
-
Track visceral fat
Visceral fat sits around your organs and is linked to insulin resistance and heart risk. You can't see it in the mirror or on a BMI chart. DEXA estimates it directly.
-
Set a training baseline
Know your lean mass for each arm and leg, spot left and right imbalances, and judge a cut or a bulk by what actually changed.
-
Protect muscle in midlife
Muscle mass declines with age, and faster around menopause. A scan gives you a number to protect instead of a guess.
Not the right test if
-
You want to check for osteoporosis
This scan reads bone across your whole body, which guidelines don't use to diagnose osteoporosis. For that, order the DEXA Bone Density Scan of your hip and spine.
-
You're pregnant or might be
DEXA uses a very small X-ray dose, so it isn't done during pregnancy.
-
You've had a barium or contrast exam recently
Leftover contrast skews the reading. Fitnescity Health partner centers need 7 days to have passed, and BodySpec asks for 2 weeks.
Do I need a referral?
No. You order online. If a partner center requires a physician's order, it is arranged for you.
Fitnescity Health or BodySpec: what's the difference?
Either way you get a whole-body DEXA scan of fat, lean mass and bone. The difference is where you go and what comes with the scan. Fitnescity Health books you into a fixed-site hospital system, imaging center or vetted wellness facility. Every site must meet its Clinical Integrity Standard: no mobile units, trained and accredited technologists following its quality protocols, and a physician review of every scan, included in the price. BodySpec scans you in its own studios in California, Colorado, Illinois, Massachusetts, Texas and Washington, and also runs mobile vans with a different scanner. Different machines can give slightly different numbers, so rescan at the same location to track change. Prices differ by provider, and if both serve your state you can switch in your cart.
Does insurance cover it?
Almost never. Body composition scans are elective, so plan to pay out of pocket.
Can I pay with my HSA or FSA?
Yes. You can pay with your HSA or FSA card at checkout.
How soon do I get results?
Fitnescity Health partner center reports come straight to your Mito dashboard, usually within 24 hours and officially within 2 business days. BodySpec results are usually ready the same day, and you add them to your Mito dashboard after your visit.
How to prepare
- One layer of comfy, metal-free clothing over underwear (think leggings + sports bra or T-shirt).
- Remove all jewelry, belts, smart-watches, wearables, and metal hairpins.
- Drink water normally, but avoid drinking a lot right before your appointment.
- The most important thing is to do the same thing at every visit, so if you arrive fasted, do so each time.
- Avoid intense exercise and sauna/steam sessions for at least 12 hours before your test.
- Check in 5 mins early. Shoes off, pockets empty, jewelry/watch/wearables off, hair down.
- If you have had a barium or contrast-dye exam, schedule your test at least 14 days after it.
What members say on Trustpilot
What the DEXA Body Composition Scan measures
DEXA, short for dual-energy X-ray absorptiometry, passes two very low-dose X-ray beams over your body while you lie still on an open table. Fat, lean tissue and bone absorb the beams differently, so the scan can tell them apart and map where each one sits. Research labs and sports medicine clinics use it as the reference method for body composition.
Bathroom scales and smart scales estimate body fat from your weight or a small electrical current, and their readings swing with how much water you're carrying. DEXA measures tissue directly, region by region, which is why it is the scan people repeat to track real change.
The radiation dose is tiny: a small fraction of a chest X-ray, and less than a day of natural background radiation.

Your results
What your DEXA Body Composition Scan report shows
Percentiles compare you with people of your age and sex. Change over time on the same machine tells you more than any single number.
Body fat percentage
Your total fat as a share of body weight, with a percentile for your age and sex. The headline number for any recomposition goal.
Lean mass
Muscle, organs and water: everything that isn't fat or bone. The number to protect while losing weight and to grow while training.
Visceral fat
An estimate of the fat packed around your organs, the type most linked to insulin resistance and heart risk. It often falls faster than total fat when habits change.
Arms, legs and trunk
Fat and lean mass for each arm, each leg and your trunk, so you can see where you carry fat and spot left and right imbalances.
Belly and hip fat
Fat around your middle (android) compared with your hips (gynoid). A higher middle share is linked to higher metabolic risk.
Whole-body bone density
A bone reading across your whole skeleton compared with people your age. Useful context, not an osteoporosis test.
What this scan can't tell you
- It doesn't diagnose osteoporosis. That takes a bone density scan of your hip and spine.
- Visceral fat is an estimate. It tracks change well but isn't a diagnosis on its own.
- Food, fluids and hard training can affect lean mass measurements, which is why preparation matters.
- Numbers from different machines or brands aren't directly comparable.
