Visceral fat is the fat stored deep in your abdomen, around organs like the liver and intestines. It raises the risk of high blood pressure, type 2 diabetes, heart disease, fatty liver and certain cancers. It can do this even when your weight and BMI look normal. The good news is that it responds to exercise and modest weight loss, and you can track it over time.
TL;DR
- Visceral fat sits around your organs and is linked to heart disease, diabetes, stroke, fatty liver, sleep apnea, certain cancers and earlier death.
- You can carry too much of it at a normal weight. Waist size and waist-to-hip ratio can flag it when BMI does not.
- Waist circumference above 40 inches (men) or 35 inches (women) is the commonly used warning line.
- Exercise reduces visceral fat even when the scale barely moves, and a 5 to 10 percent weight loss can improve metabolic health.
- A DEXA scan estimates visceral fat, and repeating it lets you see your own trend.

What visceral fat is and why it matters more than the fat you can pinch
Body fat comes in two main storage types. Subcutaneous fat sits under the skin: it is the layer you can pinch on your belly, hips or thighs. Visceral fat sits inside the abdominal cavity, packed around organs. You cannot grab it, and a soft belly does not tell you how much of it you have.
The location is what makes it a problem. According to ABC News chief medical correspondent Dr. Tara Narula, a cardiologist, fat stored around organs may lead to metabolic dysregulation. That means more inflammation and higher blood pressure, blood sugar and cholesterol levels. The American Heart Association adds that abdominal obesity is linked to fat accumulating around the liver, which often leads to non-alcoholic fatty liver disease and adds to cardiovascular risk.
A 2004 review in the medical literature proposed a useful way to think about it: a critical visceral fat threshold. Once you exceed it, metabolic disturbances such as insulin resistance may follow. The threshold differs from person to person, which is one reason two people with the same weight can have very different health profiles.
The health risks of excess visceral fat
Mayo Clinic states that, whatever your overall weight, a large amount of belly fat raises the risk of:
- High blood pressure
- Unhealthy blood fats (cholesterol and triglycerides)
- Sleep apnea
- Heart disease
- High blood sugar and type 2 diabetes
- Certain cancers
- Stroke
- Fatty liver
- Early death from any cause
The CDC’s waist guidance, as summarized by Verywell Health, extends the list of obesity-related conditions linked to a large waist to insulin resistance, hyperlipidemia, dementia, impaired lung function and metabolic syndrome.
Heart and metabolic risk
This is the best-documented area. The AHA describes abdominal obesity as a cardiovascular risk marker. In practice, the chain looks like this: more visceral fat, more insulin resistance, higher blood sugar and triglycerides, lower protective HDL cholesterol, and more strain on blood vessels. These are the same measurements your doctor checks in routine bloodwork, which is why a lipid panel and fasting glucose or A1C are worth repeating alongside any body scan.
Liver, sleep and other risks
Fat around the liver is tied to fatty liver disease, and Mayo Clinic lists sleep apnea among the risks of a large belly. If you snore heavily, wake unrefreshed or have been told you stop breathing in your sleep, mention your waist measurement to your doctor along with your symptoms.
Can you have a normal weight and still carry too much visceral fat?
Yes, and this is the part most people miss. BMI uses only height and weight. It cannot tell where fat sits or how much muscle you have.
The AHA scientific statement on obesity and cardiovascular disease notes that a high waist circumference in a normal-weight person may unmask higher cardiovascular risk. It also reports that, in US NHANES data, people whose waist-to-hip ratio indicated central obesity had a higher risk of cardiovascular death than people with the same BMI and no central fat.
Other findings point the same way:
- A 2020 NHANES analysis of normal-weight adults (BMI 18.5 to 24.9) found that those with a high waist index had more trunk and total body fat, less skeletal muscle, higher insulin and triglycerides, and lower HDL cholesterol than normal-weight adults with a low waist index.
- A 2019 review from the College of Family Physicians of Canada reported that people with atherogenic dyslipidemia who are centrally obese at a normal BMI face similar, and possibly higher, mortality risk than those who are centrally obese and also overweight by BMI.
- A 2026 JACC study following more than 250,000 adults for 20 years found that nearly one in five people with a normal BMI but a high waist-to-hip ratio had up to 50% higher risk of several heart outcomes, including heart attack, stroke and heart failure.
- In adults aged 70 to 79, a 2005 study of 3,035 people found visceral fat was associated with metabolic syndrome whether they were normal weight, overweight or obese.
The practical lesson: a normal BMI is not a clean bill of health, especially if your waist has been growing while your weight stays put. This often happens with age, low muscle mass, long desk hours or a period of reduced training.
How visceral fat is measured
No single test is perfect, so it helps to combine a few.
Waist circumference and waist-to-hip ratio
The simplest check is a tape measure at home. In the US, many clinicians and researchers have accepted a single threshold of 102 cm (about 40 inches) for men and 88 cm (about 35 inches) for women to denote a high waist circumference, regardless of BMI. Measure at the level of your navel, relaxed, after a normal exhale, with the tape snug but not pressing into the skin. If you want to put these numbers in context of your overall plan, these weight management guides cover waist thresholds and related habits.
Waist-to-hip ratio adds another view. The AHA statement says it predicts cardiovascular mortality independently of BMI.
Blood markers
The same Lancet Diabetes & Endocrinology position statement notes that an increased waist plus increased triglycerides has been associated with a high probability, around 80%, of increased visceral fat. That is a cheap screen you can discuss with your doctor.
DEXA scans
A DEXA scan gives you body fat percentage, lean mass, bone density and an estimate of visceral fat in one visit. The Lancet position statement notes that DEXA might slightly underestimate visceral fat in normal-weight individuals and overestimate it in people with very severe obesity. That makes the trend between scans, done on the same type of machine and under similar conditions, more informative than any one number. If you are new to the technology, our guides explain what a DEXA scan is and what a DEXA scan measures.

Why visceral fat can seem stubborn after weight loss
Many people lose weight and still wonder whether their visceral fat moved. Several things can be going on, and the research offers some honest context.
Fat cells do not disappear. A study by Spalding and colleagues found that fat cell numbers stay constant in adulthood, even after marked weight loss, with roughly 10% of fat cells renewed each year. Cells shrink when you lose weight but remain available to refill.
Fat tissue may keep a memory. A 2020 mouse study described “obesogenic memory”: inflammation and insulin resistance in fat tissue persisted after body weight and fat normalized. It was an animal study, so it is a reason to keep up healthy habits, not a prediction for any one person.
The scale and the waist are different measures. Visceral fat can drop while weight barely changes, particularly when you gain muscle at the same time. The Canadian review cites 11 of 29 exercise trials showing a significant reduction in visceral fat despite no clinically relevant weight loss, and states that visceral fat is preferentially lost in people with minimal weight loss under exercise-based programs.
Scan-to-scan variation is real. A single visceral fat reading can shift with hydration, food intake and positioning, and DEXA estimates carry a margin of error. Look at several scans, not one.
What actually lowers visceral fat
The evidence favors movement first, and then a modest calorie reduction.
- Exercise regularly. The AHA reports that aerobic exercise is the most beneficial for reducing abdominal obesity, and that meeting the 150 minutes per week recommendation may be sufficient. A meta-analysis cited in the Canadian review found that, with weight held stable, exercise reduced visceral fat by 6.1% and diet by 1.1% over 4 to 52 weeks.
- Trim calories moderately. The AHA says reducing calories can reduce abdominal fat. The 2004 review found metabolic profiles in visceral obesity may improve after modest weight loss of 5 to 10 percent of body weight. For a 200 lb person, that is 10 to 20 lb.
- Combine both. The AHA notes that exercise, or exercise plus dietary change, can reduce abdominal obesity in some cases even without weight loss. It also states that lifestyle studies have not yet shown a reduction in coronary events like heart attack, so keep up your regular checkups and any prescribed treatment.
- Track the right numbers. Weight alone hides what you are after. Waist, waist-to-hip ratio, bloodwork and periodic body composition scans show whether the change is happening where it counts. Our piece on how long it takes to lose 1% body fat gives a realistic sense of the timeline.
If you have diabetes, heart disease or high blood pressure, or take medication for them, talk with your doctor before making big changes to your diet or exercise routine.
Our perspective
Most people judge their health by the scale, and that is the number least able to answer the question you actually care about: where is my fat, and is it changing? Visceral fat is the clearest example. Two people can weigh the same and carry very different amounts around their organs.
A DEXA scan gives you that detail, but the PDF you get at the clinic is hard to read, and a single result says little. The value shows up when you line scans up over time: visceral fat, lean mass, body fat percentage and bone density moving together. That is what we built DEXA.report to show, in plain language, from reports from any clinic, without retyping numbers.
We also think health data should stay yours. Your dashboard is accessible only to you, and your data is stored in the EU. You get the insight, and no one else gets your scan.

FAQ
Why is visceral fat dangerous?
It surrounds your organs and, according to cardiologist Dr. Tara Narula, may drive metabolic dysregulation: more inflammation and higher blood pressure, blood sugar and cholesterol. Fat around the liver is also linked to fatty liver disease. Mayo Clinic lists heart disease, diabetes, stroke, certain cancers and early death among the associated risks.
Can I have a flat stomach and still have visceral fat?
Yes. Visceral fat is deep, so a flat or average-looking belly does not rule it out. The AHA says a high waist circumference or waist-to-hip ratio can signal higher heart risk even in healthy-weight people. Measuring your waist and checking bloodwork gives a better picture than the mirror.
What waist size signals higher risk?
The commonly used lines are above 40 inches (102 cm) for men and above 35 inches (88 cm) for women. The CDC links exceeding them with higher risk of type 2 diabetes, cardiovascular disease and high blood pressure. These are screening thresholds, so your doctor will interpret them with your other results.
Why hasn’t my visceral fat dropped after I lost weight?
Fat cells shrink but do not vanish, and visceral fat can respond more to exercise than to diet alone. DEXA estimates also vary a little between scans. Compare several scans over time, and keep up aerobic exercise, which the AHA identifies as most beneficial for abdominal fat.
