Visceral Fat
Fat stored around internal organs — the most dangerous type of body fat.
Plain English
Patient-Friendly Explanation
Visceral fat is the deep belly fat that wraps around your liver, pancreas, and intestines. Unlike fat under your skin, this type actively produces harmful substances and raises disease risk.
Medical
Clinical Definition
Visceral adipose tissue (VAT) is metabolically active, secreting pro-inflammatory adipokines (TNF-α, IL-6) and contributing to insulin resistance. VAT area > 100cm² on CT is considered elevated.
Key Insight
Why It Matters
Reducing visceral fat — even without major weight loss — significantly improves metabolic health. Exercise and GLP-1 agonists are particularly effective at reducing VAT.
What visceral fat is
Visceral fat is the fat stored deep inside the abdomen, wrapped around the liver, pancreas and intestines — the fat you cannot pinch. It is different from subcutaneous fat (the pinchable layer under the skin). Visceral fat is metabolically active tissue that releases inflammatory signals directly into the bloodstream.
Why it is the dangerous fat
Visceral fat is the strongest fat-related predictor of metabolic disease:
- Insulin resistance and type 2 diabetes — visceral fat interferes with insulin signalling
- Raised blood pressure and unhealthy cholesterol patterns
- Fatty liver — visceral fat drains directly into the liver
- Heart disease and stroke risk independent of BMI
- Sleep apnoea and joint strain
How it is measured
You don't need a scan to know you're at risk, but measurements make it objective:
- Waist circumference — the practical first check (Asian cut-offs: 90 cm men, 80 cm women)
- InBody/BIA scan — gives a visceral fat level (1–59 scale; under 10 is healthy, 10–14 is high, 15+ is very high)
- MRI/CT — the research gold standard, not needed clinically
How to lose visceral fat
The good news: visceral fat is usually the FIRST fat to mobilise when you create a calorie deficit. The bad news: it comes back fast with regain, so consistency matters:
- A calorie deficit — even 5% weight loss measurably shrinks visceral fat
- Exercise — both walking and resistance training reduce visceral fat; exercise seems to target it preferentially
- Less added sugar and alcohol — both are preferentially stored as visceral fat
- Adequate sleep and stress management — cortisol and short sleep drive abdominal storage
Common questions
What is a healthy visceral fat level?
On the InBody scale (1–59), under 10 is healthy, 10–14 is high, and 15 or above is very high. A simpler proxy is waist circumference: 90 cm or more in Asian men and 80 cm or more in Asian women indicates excess visceral fat.
How do I know if I have visceral fat?
A waist measurement or a body-composition scan. You cannot feel or pinch visceral fat — it sits behind the abdominal wall — so the tape measure and the scan are the honest ways to track it.
Can you lose visceral fat without losing weight?
Partially. Exercise can reduce visceral fat even when the scale barely moves, because it is the most metabolically responsive fat depot. But the most reliable route is a calorie deficit plus activity — the two together shrink it fastest.
How long does it take to lose visceral fat?
Visible reductions in waist circumference usually appear within 4–8 weeks of a consistent plan, and visceral fat falls proportionally faster than overall weight in the early phase. The clinic tracks it with InBody scans so progress is objective.
