What does visceral fat mean on a DEXA report?
Visceral adipose tissue, often shortened to VAT, refers to fat inside the abdominal cavity. Some DEXA systems estimate this as part of body composition analysis. The report may show an area, mass or volume, depending on the equipment and software.
Start by identifying the exact measurement and its units. An area in cm² and a mass in grams describe different quantities. They should not be compared as though they were the same number.
Is android fat the same as visceral fat?
No. Android is a report region around the abdomen. It includes fat beyond the visceral compartment. An android-to-gynoid ratio compares defined report regions and is a different measure from a VAT estimate.
Use the labels and definitions supplied with your report. If the report shows several abdominal measurements, ask which one the practitioner is discussing.
What is a healthy visceral fat number?
This guide does not supply a universal cut-off. Interpretation needs the scanner’s method, units, relevant reference data and your health context. A coloured flag on a report is a prompt for a conversation, not a diagnosis by itself.
Ask your GP how the finding fits with your history and any other assessments. Avoid using a number copied from another scanner’s report to choose treatment or set a personal target.
Comparing visceral fat between scans
Keep the original reports and check that the same estimate and units appear on both. Ask about the scanner, software, preparation and whether the observed difference is larger than expected measurement variation.
For example, a report labelled ‘VAT area’ and one labelled ‘VAT mass’ cannot establish an increase or decrease simply by comparing their numbers. First ask the clinic whether a valid comparison is available.

Find the matching reference before setting a goal
Use the scanner-specific visceral-fat guide to check the measurement and units. A population median is not a risk boundary or a personal target. Bring the full report to your GP before deciding what, if anything, needs to change.
If a repeat measurement is useful, agree on the question and timing with your practitioner. Keep preparation and scanner details with both reports. Avoid using a result from another scanner family as a direct comparison.
At your appointment
- What does this scanner’s visceral fat estimate mean?
- Does it change anything about my current health assessment?
- Would any other assessment be useful before changing my plan?
A sensible next step
Start with your GP. A dietitian can help with a nutrition plan if that is appropriate for you.
These suggestions are general information. Your own practitioner can review the full report and your history.
