How do I know if I have visceral fat?
On this page
Measure your waist. Visceral fat sits deep in your belly, around your liver and gut, so you can’t pinch it or see it in a mirror. A waist over 40 inches for a man or over 35 inches for a woman raises your risk of heart disease and type 2 diabetes. A tape tells you more than your weight does.
Why it’s easy to miss
Two people can weigh the same and carry very different amounts of fat inside. A normal weight doesn’t rule it out. In a 2025 study of 471,228 adults in 91 countries, 21.7% of people with a normal BMI had a big waist. Compared with normal-weight people with a normal waist, they had 81% higher odds of diabetes and 29% higher odds of high blood pressure. That study counted a waist of about 37 inches for men or 31.5 inches for women as big.
How to measure
- Stand up straight and breathe out.
- Put the tape around your bare middle, just above your hip bones. Keep it level and snug, without pressing in.
- Compare it with 40 inches for men and 35 inches for women, or use the waist check.
A waist tape is like a smoke alarm. It can’t show you the fire, but it’s cheap and it tells you when to act.
What about the number on my scale?
Treat a home scale’s visceral fat number as a rough estimate. In a 2023 lab test of 15 devices, the same scales missed total bodyfat by several points. A CT or MRI scan can measure visceral fat directly, but you don’t need one to act on a big waist.
Can you get rid of it?
Yes. A 2017 review of 89 studies found visceral fat falls by a bigger share than the fat under your skin when you lose weight, whatever the method. So the same plan that takes off any fat shrinks it first: eat a little less, lift and walk, and check the tape once a month.
