What is visceral fat, and how do you lose it?
Visceral fat is the fat stored deep in your belly, around the liver, gut and other organs, as opposed to the soft subcutaneous fat under your skin. Too much of it raises the risk of type 2 diabetes, heart disease and fatty liver. You can't see it directly, but a waist bigger than half your height is a good sign you're carrying too much. It responds well to change: regular exercise and a calorie deficit both reduce it, often faster than other fat.
Visceral vs subcutaneous fat
| Visceral fat | Subcutaneous fat | |
|---|---|---|
| Where | Inside the abdomen, around the organs | Under the skin, the part you can pinch |
| Feels | Firm belly that pushes out | Soft, pinchable |
| Health risk | High: linked to diabetes, heart disease, fatty liver | Lower, especially on hips and thighs |
| Who has more | Men; women after menopause; older adults | Women before menopause |
| How it responds | Shrinks early with exercise and a deficit | Shrinks more slowly |
How to measure visceral fat
- Waist-to-height ratio: the easiest and well-validated check. Under 0.5 is healthy; 0.6 or more is high risk. Use the box above.
- Waist alone: above 94 cm (37.0 in) for men or 80 cm (31.5 in) for women means increased risk; above 102 cm (40.0 in) and 88 cm (34.5 in), high. People of South Asian, Chinese and Japanese origin carry more visceral fat at the same waist, so lower cut-offs apply (about 90 cm for men).
- DEXA, CT or MRI scans measure it directly; DEXA is the most available.
- Smart scales show a "visceral fat rating", but it's an estimate from your weight, height and age, and it isn't precise enough for one person.
| Height | Healthyunder 0.5 | High risk0.6 and over |
|---|---|---|
| 155 cm 5′1″ | under 78 cm 30.5 in | 93 cm 36.5 in |
| 160 cm 5′3″ | under 80 cm 31.5 in | 96 cm 38.0 in |
| 165 cm 5′5″ | under 83 cm 32.5 in | 99 cm 39.0 in |
| 170 cm 5′7″ | under 85 cm 33.5 in | 102 cm 40.0 in |
| 175 cm 5′9″ | under 88 cm 34.5 in | 105 cm 41.5 in |
| 180 cm 5′11″ | under 90 cm 35.5 in | 108 cm 42.5 in |
| 185 cm 6′1″ | under 93 cm 36.5 in | 111 cm 43.5 in |
| 190 cm 6′3″ | under 95 cm 37.5 in | 114 cm 45.0 in |
How to lose visceral fat
- Move every day. In a large review, aerobic exercise reduced visceral fat even with little weight loss; walking counts (steps to lose weight).
- Eat in a calorie deficit. Diet causes more weight loss than exercise; together they work best (calorie deficit calculator).
- Lift weights to keep muscle while you lose fat.
- Cut back on alcohol and sugary drinks, both linked with more fat around the liver.
- Sleep 7–9 hours: short sleep is linked with more visceral fat and more hunger.

How fast does visceral fat go?
Faster than most fat. Scans show visceral fat falling within weeks of starting regular exercise or a diet, and losing about 5–10% of your weight often cuts it by a larger share than that. Your waist is the practical way to follow it: measure every 2–4 weeks.
Visceral fat and body fat percentage
Total body fat and visceral fat usually move together, but not always: some slim people carry a lot of visceral fat (sometimes called "thin outside, fat inside"). Relative fat mass, from your height and waist only, estimates total body fat: a woman of 165 cm with an 88 cm waist comes out at about 39%, a man of 178 cm with a 102 cm waist at about 29%. Compare methods in the body fat calculator; for the ranges, see healthy body fat percentage, and for normal-weight people with high body fat, skinny fat.
