The Hidden Fat You Can’t See But Shouldn’t Ignore
When most people think about fat, they imagine the soft tissue under their skin that changes how clothes fit. Yet the most dangerous kind of fat lies deep inside the body. Visceral fat surrounds vital organs like the liver, pancreas, and intestines, and it is far more metabolically active than the fat you can see. This hidden fat promotes inflammation, insulin resistance, and artery damage that increase the risk of heart attack and stroke.
A large study from Canada and the United Kingdom found that higher amounts of visceral and liver fat were strongly linked to carotid atherosclerosis, a thickening and narrowing of the arteries that deliver blood to the brain. The researchers discovered that this relationship held true even after adjusting for traditional cardiovascular risk factors such as blood pressure, cholesterol, and BMI. This means a person can appear to have a healthy weight while still facing a serious risk of cardiovascular disease if they carry excess visceral fat.
Why BMI Alone Doesn’t Tell the Full Story
BMI, or Body Mass Index, has long been the standard for assessing body weight relative to height. While easy to calculate, BMI does not distinguish between fat and muscle or indicate where fat is distributed in the body. Two people may share the same BMI, yet one may carry significantly more visceral fat and have a much higher cardiovascular risk.
Recent findings show that visceral fat is more closely tied to artery thickening, high blood pressure, type 2 diabetes, and cognitive decline than BMI or even total body fat. It is the fat’s location—around organs and blood vessels—that makes it so dangerous.
Why Visceral Fat Is So Harmful
Visceral fat releases inflammatory molecules and hormones that travel through the bloodstream, damaging artery walls and disrupting metabolism. Over time, these changes lead to plaque buildup, reduced circulation, and a higher chance of developing conditions such as:
-
Hypertension
-
Dyslipidemia (abnormal cholesterol levels)
-
Insulin resistance and diabetes
-
Cognitive decline and dementia
Visceral fat acts almost like a separate organ, driving inflammation and accelerating the aging process.
The Study Linking Visceral Fat to Artery Damage
In this recent large-scale study, researchers used data from two cohorts: the Canadian Alliance for Healthy Hearts and Minds (6,760 participants) and the UK Biobank (26,547 participants). Both groups included men and women with an average age in the mid-50s.
To measure fat and artery health, researchers used MRI scans of the abdomen and carotid arteries in the Canadian group and ultrasound in the UK group. These precise imaging tools revealed that visceral fat and liver fat were associated with thicker artery walls, even after controlling for blood pressure, cholesterol, and other common cardiovascular risk markers.
The consistency of the findings across two independent populations provides strong evidence that visceral fat is a major driver of cardiovascular damage, independent of weight or BMI. However, most participants were of European descent, which limits how broadly the results can be applied across all populations—a point the authors acknowledged as a study limitation.
Lifestyle Changes That Reduce Visceral Fat
The good news is that visceral fat can be reduced through simple, sustainable changes. Even modest weight loss or improved fitness can have a large impact on reducing organ fat and improving metabolic health.
Nutrition Strategies
-
Focus on a Mediterranean-style diet rich in vegetables, fruits, whole grains, lean proteins, and healthy fats like olive oil.
-
Limit processed foods, refined carbohydrates, and added sugars that trigger fat storage and inflammation.
-
Avoid fried and heavily processed foods that contribute to insulin resistance.
-
Consider time-restricted eating, which has been shown in studies to improve fat metabolism and reduce liver fat.
Exercise Recommendations
-
Engage in at least 150 minutes of moderate-intensity aerobic activity per week, such as brisk walking or cycling.
-
Include two or more strength training sessions weekly to preserve muscle mass and improve insulin sensitivity.
-
Add short bursts of higher-intensity activity if tolerated, as these have been shown to target visceral fat effectively.
Additional Lifestyle Factors
-
Prioritize sleep, as poor rest increases stress hormones linked to fat storage.
-
Manage stress through mindfulness, yoga, or deep breathing exercises to lower cortisol levels.
-
Avoid excessive alcohol intake, which can increase liver fat accumulation.
How to Measure Visceral Fat Accurately
Unlike BMI or waist circumference, DEXA body composition scans offer a precise, clinically validated method to measure visceral fat. At Healthspan Longevity, DEXA scans provide a detailed report showing exactly how fat, muscle, and bone are distributed throughout the body.
A DEXA scan identifies how much visceral fat is stored around your organs, helping you understand your true cardiovascular and metabolic risk. This test takes only a few minutes and provides far more actionable insight than a scale or tape measure.
Why DEXA Scans Are Superior
-
They distinguish between subcutaneous and visceral fat.
-
They provide a baseline for tracking changes over time.
-
They help tailor lifestyle interventions to your specific body composition.
-
They identify early warning signs before symptoms or lab results change.
Knowing your visceral fat level empowers you to take action early, preventing disease and extending your healthspan.
Frequently Asked Questions About Visceral Fat and DEXA Scans
What is visceral fat?
Visceral fat is the fat stored deep inside your abdomen around internal organs such as the liver, pancreas, and intestines. It differs from subcutaneous fat under the skin and is linked to inflammation, artery damage, and higher cardiovascular risk.
Why is visceral fat more dangerous than regular fat?
Visceral fat releases inflammatory compounds that damage blood vessels and disrupt metabolism. This increases the risk of heart disease, type 2 diabetes, and stroke, even in people who appear to be a healthy weight.
How can visceral fat be measured accurately?
The most precise method is a DEXA body composition scan, which separates visceral fat from other fat types and provides an exact measurement of internal fat stores.
Can visceral fat be reduced naturally?
Yes. Regular physical activity, balanced nutrition, quality sleep, and stress management are the most effective ways to reduce visceral fat. Even a 5–10% reduction in total body weight can significantly lower organ fat levels.
How often should visceral fat be checked?
Most adults benefit from checking visceral fat once or twice a year. A DEXA scan helps monitor progress and confirms whether your lifestyle changes are successfully lowering hidden fat.
Take Control of Your Cardiovascular Health with a DEXA Scan
If you’ve been told your BMI is normal but still experience high cholesterol, blood pressure, or blood sugar, hidden visceral fat could be the underlying cause. Even individuals who appear lean can have dangerous amounts of organ fat.
Schedule a DEXA scan at Healthspan Longevity to measure your visceral fat and gain a clear picture of your cardiovascular risk. Early detection allows you to make targeted lifestyle changes that protect your heart, brain, and overall longevity.
Taking a DEXA scan is one of the most powerful steps you can take for preventive health. The sooner you know your numbers, the sooner you can make informed choices that improve vitality, energy, and quality of life. Book your DEXA scan today and discover how much visceral fat you have—and what you can do to reduce it.
