Visceral Fat Level on a Body Composition Scan, Explained Calmly
The visceral fat level on a body composition scan is an estimate of how much fat is stored deep in your abdomen, around the organs, rather than under the skin. On an InBody scan it is shown as a level on a scale of 1 to 20, and the manufacturer treats a level below 10 as the normal range for adults, with lower being better. It is a useful prompt, not a diagnosis. The number responds to the same habits that reduce body fat generally, and it is best read alongside your waist measurement and over several scans rather than on its own.
People often see a high number for the first time and assume the worst. That is understandable, and usually not warranted. Here is what the number means, what it does not, and what tends to move it.
Visceral fat and subcutaneous fat: the difference
Most body fat sits just under the skin. That is subcutaneous fat, the kind you can pinch. Visceral fat sits inside the abdominal cavity, packed around the liver, intestines and other organs. You cannot pinch it, and someone can carry a fair amount of it while looking only moderately overweight, or even slim.
The distinction matters because visceral fat is more closely associated with health risks such as type 2 diabetes and heart disease than fat stored elsewhere. That association is why the NHS and NICE pay attention to waist size, not just weight.
How the scan arrives at the number
An InBody scanner sends a very small electrical current through the body via the hands and feet and measures resistance. Water conducts well and fat does not, so from that and your height, weight, age and sex, it estimates lean mass and fat mass in each body segment. The visceral fat level is then estimated from the trunk readings and those inputs.
The word that matters is “estimated”. The scan does not image your organs. Medical imaging such as MRI or CT can measure visceral fat directly; a bioimpedance scanner predicts it. That makes the number very good for tracking change over time under consistent conditions, and less reliable as an absolute value for any one person. Our piece on reading the full InBody sheet explains where this number sits among the others.
Reading your level
| Level | How to read it |
|---|---|
| 1-9 | Within the range the manufacturer treats as normal. Keep doing what you are doing. |
| 10-14 | Above that range. Worth acting on through training, food, sleep and alcohol habits. Check your waist measurement too. |
| 15 and above | Well above the normal range. A good reason to speak to your GP, who can look at blood pressure, blood sugar and cholesterol, which a scan cannot. |
A one-level change between two scans is within normal variation. A steady trend of several levels over a few months is meaningful.
Check it against your waist
You can sanity-check the scan with a tape measure. NICE advises keeping your waist measurement to less than half your height: someone 180 cm tall would aim for a waist under 90 cm. To measure, find the point halfway between your lowest rib and the top of your hip bone, breathe out normally, and measure without pulling the tape tight.
If the scan and the tape agree, you can be fairly confident in the picture. If they disagree, trust the trend in both over the next couple of months rather than either single reading.
What makes the reading wobble
Because the scanner relies on body water, anything that changes hydration changes the result. Common culprits:
- A large meal or a lot of fluid shortly before the scan
- Training hard in the previous few hours
- Alcohol the night before
- Starting creatine, which increases water held in muscle
- Different times of day between scans
Scan at the same time of day, before eating and before training, ideally after using the toilet. Our guide on preparing for an InBody scan has the full checklist.
What brings visceral fat down
There is no exercise or food that targets visceral fat specifically. It tends to come down with overall fat loss, and often responds relatively early when habits improve. The things that reliably help:
- A modest, sustainable calorie deficit. Not a crash diet. Something you can keep up for months.
- Regular physical activity. The UK guidelines suggest at least 150 minutes of moderate activity a week. Walking counts.
- Strength training two or more times a week. It helps preserve muscle while you lose fat, so the weight that comes off is mostly fat.
- Enough sleep. Short sleep makes appetite harder to manage and training harder to recover from.
- Moderating alcohol. It adds calories easily and tends to lead to worse food choices. Our post on alcohol and fat loss covers how to approach it without giving up entirely.
- Enough protein and fibre. Both help with fullness, which makes the deficit easier to sustain.
Crunches will not do it. Training the abdominal muscles does not burn the fat sitting around or beneath them.
How long change takes
With consistent habits, most people see the visceral fat level start to move within two to three months. Scanning more often than every four weeks mainly measures day-to-day water changes. A sensible rhythm is a baseline scan, then one every four to eight weeks.
How we use the number in the studio
The studio under The Highgate House has an InBody scanner, and clients are scanned at the start and at regular intervals after that. We do not treat visceral fat as a score to beat. It is one line on a sheet that helps us decide whether the plan is working, alongside strength, waist, energy and how training feels. If the number is high, we will suggest a GP check rather than pretend a training plan replaces one. If you would like a scan as part of coached training, see personal training in Highgate.
Check with your GP first before starting a new training programme if you have a heart condition, diabetes, high blood pressure, are pregnant or have not exercised for a long time. Body composition scans of this kind are also not suitable for people with pacemakers or other implanted electronic devices.
Questions we get asked
Can you be slim and have high visceral fat?
Yes. Some people carry relatively little fat under the skin but more around the organs. It is one reason waist size and scans can be more informative than weight alone.
Is visceral fat harder to lose than other fat?
Generally not. It often responds relatively early to improved habits, though everyone loses fat in a slightly different order.
Is a level of 10 dangerous?
It is at the edge of the range the manufacturer considers normal. On its own it is a prompt to look at habits and your waist measurement, not a cause for alarm.
How often should I be scanned?
Every four to eight weeks is plenty for most people. With 1-1 coaching, we time scans around your plan so readings are comparable.
