What Is a DEXA Body Composition Scan?

15th Oct 2025

A DEXA Scan (Dual-Energy X-ray Absorptiometry) is a fast, non-invasive imaging test that delivers a detailed analysis of your body composition. Unlike regular scales or BMI calculators, a DEXA scan can accurately measure:

  • Total and regional body fat

  • Lean muscle mass

  • Bone mineral density

The scan takes just 10–15 minutes, is painless, and provides a comprehensive report showing exactly where fat and muscle are distributed throughout your body.

Why DEXA Scans Are Important for Weight Loss

A DEXA Body Composition Scan offers insights that help guide your weight loss journey with precision:

  • Track true fat loss – Know whether you’re losing fat, muscle, or water.
  • Set realistic goals – Understand your baseline body composition and target areas for improvement.
  • Monitor progress accurately – Repeat scans can measure changes over time to see how your diet, exercise, or medical treatment is working.
  • Optimise your metabolism – Identifying lean muscle mass helps your doctor recommend ways to preserve or build muscle to improve metabolism and long-term fat loss.

Why a DEXA Scan Is a Game-Changer for Weight Loss

Using a DEXA Body Composition Scan gives you a clear and accurate picture of your progress, so you can make smarter health decisions. Here’s how it helps:

  • Track real fat loss — Know whether you’re losing fat, muscle, or just water weight.

  • Set realistic weight loss goals — Understand your baseline and target specific areas.

  • Monitor progress over time — Compare scans to see the true impact of your diet, exercise, or medical program.

  • Boost your metabolism — Identifying lean muscle helps preserve or build it, which supports long-term fat loss.
