How It Works

What is a DXA body composition analysis scan?

A DXA body composition analysis scan is a full-body scan using dual-energy X-ray absorptiometry (measuring the absorption of energy from two different X-rays to assess the density of living tissue).

  • Fast
  • Painless
  • Accurate
  • Actionable

We use mobile Hologic® Horizon™ DXA scanners to assess complete body composition. These medical-grade scans are the most reliable way to take the guesswork out of physiological metrics.

Your first scan

provides detailed baseline health and fitness data.

Repeat scans

let you track the results of your nutrition and training plan over time.

How DXA Scanning works

DXA technology body composition analysis is:

  • FDA approved
  • Safe for individuals with pacemakers
  • Significantly more accurate than other body scanning technology
  • Used by professional sports teams, universities and elite sports labs nationwide
DXA scans show you the precise location of bone mass, lean muscle, and fat in the body

How it works

During a DXA body composition scan you remain fully clothed and lie on your back on a flat, open platform. All you have to do is stay still for about 6 minutes.

A scanning arm passes slowly over your body, using low-dose X-ray beams - one high-energy beam, and one low-energy beam. The scanner measures the amount of X-rays from each beam that pass through your body. The difference between the two beams determines body composition.

Fat, muscle, and bone mineral content is recorded for each image pixel location throughout your entire body. You get your results immediately after the scan

  1. Remain fully clothed & lie on your back
  2. Stay still for 6 minutes during the scan
  3. Get your results immediately


How low is “low-dose” radiation?

An average BodyData scan exposes you to 0.4 microsieverts (μSv) of radiation.

An average person is exposed to around 10 μSv of radiation every day from natural background sources (such as radon in the air, radiation from the earth, and cosmic radiation).

DXA, weight loss & your health

DXA body composition scanning measures two types of fat:

Subcutaneous fat is just beneath your skin (fat you can pinch).
Visceral adipose tissue (VAT) is hidden behind the abdominal wall, packed around your internal organs.

A “skinny fat” person can have a healthy BMI, and still have an unhealthy amount of visceral adipose tissue.

How VAT harms your health

Too much VAT is terrible for your resting metabolism. Worse, VAT constantly produces inflammatory chemicals including hormones and cytokines (cell-signaling protein molecules).

High VAT levels have a toxic effect on the body, and are associated with an elevated risk of the “Big 4” diseases:


High levels of VAT can lead to metabolic syndrome, insulin resistance and diabetes.


Excess visceral fat causes inflammation, which has been shown to impair cognitive function.

Heart Disease

The liver metabolizes visceral fat, turning into cholesterol, which collects as plaque in arteries.


Multiple studies have established a link between visceral obesity and a higher cancer risk.

Know your risk - see the results

DXA body composition analysis scans show you exactly where and how much subcutaneous and visceral fat is in your body – as an overall percentage, and in specific areas.

Tracking fat loss using body composition scanning helps you customize your diet and exercise plan to make sure you’re losing the right kind of weight.

DXA for athletes

Elite sports labs (pro and collegiate) use DXA body composition analysis scans to:

  • Critically analyze progress
  • Identify muscle imbalances
  • Monitor injury recovery during rehab
  • Optimize performance with personalized insights

BodyData scans help fitness professionals provide better guidance. Personal trainers can monitor clients’ progress and optimize workouts based on the results. Coaches can use DXA body composition analysis scans to help their players prevent injury and perform better by improving muscle symmetry.

Better data, smarter nutrition

Creating the right nutrition plan for athletes starts with precise body composition measurements. Daily caloric needs are determined by resting metabolic rate, based on muscle mass.

DXA body composition analysis scans help you eliminate guesswork and fine-tune your results. Monitoring your body composition over time reveals how your body is responding to your nutrition and meal plan.

BodyData scans reveal what’s beneath the surface so you can understand your personal long-term health risks and take action to lower them.
