When it comes to evaluating health and fitness, most people focus on weight or BMI, but those metrics don’t tell the whole story. A crucial factor often overlooked is visceral fat. Visceral fat is the deep belly fat stored around your internal organs, and it plays an outsized role in your health. Visceral fat level is considered a much better predictor of health risks than BMI or weight alone. High visceral fat has been linked to severe conditions like heart disease and diabetes, even in people who look “thin”. This article will explain what visceral fat is, how it differs from other fat, why the effects of visceral fat make it so dangerous, and how to measure and reduce visceral fat to improve your overall fitness.
Understanding Visceral Fat
Visceral fat is the body fat stored deep in your abdomen, wrapped around organs such as the liver, pancreas, intestines, and heart. The word “viscera” means internal organs. Unlike the fat just beneath your skin (subcutaneous fat), visceral fat isn’t visible from the outside, and you can’t pinch it. In normal amounts, visceral fat provides a cushion for organs and a readily available energy reserve. However, too much visceral fat becomes a silent threat. It’s “active” in that it releases hormones and inflammatory chemicals that can disrupt the body’s normal functions. For context, visceral fat percentage in a healthy individual is only about 10% of total body fat, but when it grows beyond that, health risks rise sharply.
Visceral vs Subcutaneous Fat
While excess subcutaneous fat can certainly pose health issues, it’s generally far less dangerous than visceral fat. Why? Visceral fat releases pro-inflammatory hormones and free fatty acids into the portal vein, interfering with metabolism. Visceral fat behaves like a toxic factory at the center of your body. An overabundance of visceral fat is associated with increased fitness and fat levels that strain your organs, whereas subcutaneous fat is more of a passive energy storage. This is why someone can have a fairly solid-looking “beer belly” and face greater health risks than someone of the same weight who carries fat more superficially.
Visceral Fat and Health Risks
Excess visceral fat is not just a vanity issue. It’s a medical concern. Because it surrounds vital organs, this fat can interfere with their function and trigger harmful processes in the body. People with higher visceral fat have a significantly higher risk of metabolic and cardiovascular diseases. The effects of visceral fat on the body include increased inflammation, insulin resistance, and hormone imbalances that can lead to severe conditions. Visceral fat actively secretes chemicals that raise your blood pressure, lower your good cholesterol, and impair how your body handles blood sugar. This is why visceral fat is closely tied to the development of metabolic syndrome.
Visceral fat often goes hand-in-hand with insulin resistance, a precursor to type 2 diabetes. It can also elevate cortisol (a stress hormone) and drive chronic inflammation in blood vessels. Over time, these changes translate to higher risks of conditions such as heart disease, heart attacks, stroke, type 2 diabetes, and even certain cancers. In women, excess visceral fat has been linked to higher breast cancer risk; in both genders, it’s related to colorectal cancer and liver problems. Simply put, carrying too much visceral fat is dangerous. Visceral fat can cause health issues such as high blood pressure, heart disease, type 2 diabetes, and some cancers. Even if your total weight isn’t extreme, a high proportion of visceral fat means your body is internally under strain. This is why measuring visceral fat is so important. It’s possible to have a normal BMI yet still carry excess visceral fat.
Causes of Belly Fat (Visceral Fat Accumulation)
The fundamental cause is taking in more calories than you burn, especially from certain types of foods. When you consistently eat a surplus of calories, your body stores the extra energy as fat, and the abdomen is a prime storage location for many people. Diets high in added sugars, refined carbohydrates, and unhealthy fats are strongly linked to increases in visceral fat. For example, regularly consuming sugary drinks, processed snacks, and fast food encourages visceral fat deposition. Eating fatty foods and excess carbohydrates (sugars) can make your body form more visceral fat, and if you aren’t active enough, you’ll accumulate more visceral fat than your body can burn off. A sedentary lifestyle is a major contributor to visceral fat gain.
Stress is another sneaky factor. When you experience chronic stress, your body produces more cortisol. High cortisol levels signal the body to hang on to energy reserves, often in the form of visceral fat. Unmanaged stress can lead to a “cortisol belly,” in which fat accumulates disproportionately in the midsection. Lack of sleep also ties in here; inadequate sleep can disrupt hunger hormones and metabolism, increasing the likelihood of weight gain and belly fat.
Other contributors include alcohol consumption and smoking. Heavy alcohol intake is notorious for promoting abdominal obesity because of the extra calories in alcohol and its tendency to alter fat metabolism. Smoking is associated with more visceral fat. Smokers often have more abdominal fat than nonsmokers, possibly due to smoking’s effects on hormones and fat distribution.
Genetics and hormones play a role as well. Some individuals are genetically predisposed to store fat in the visceral fat tissue rather than subcutaneously. Men, for instance, tend to accumulate a higher proportion of fat viscerally, whereas premenopausal women store more fat subcutaneously on hips and thighs. However, after menopause, women’s bodies often shift to store more fat in the abdomen, too. Aging in general is associated with increasing visceral fat, even if body weight doesn’t change dramatically, partly because of hormonal changes and a slowing metabolism.
Measuring Body Fat at Home
Some indirect methods and tools can give you clues about your body fat and where you carry it. Home methods focus on overall body composition and simple measurements, since imaging visceral fat directly requires specialized equipment. Here are some ways to assess body fat and get an idea of your visceral fat level:
-
Waist Circumference: One of the simplest indicators of visceral fat is your waist size. Measure around your waist with a tape measure. A large waist circumference is a red flag for excess visceral fat. As a rule of thumb, a waist above 35 inches (88 cm) in women or 40 inches (102 cm) in men suggests unhealthy visceral fat levels. This measure doesn’t tell you the exact amount of visceral fat, but it’s strongly correlated with it. Waist size is part of the definition of metabolic syndrome because of its link to visceral adiposity. Tracking your waist measurement over time is a quick way to see if you’re gaining or losing dangerous belly fat.
-
Waist-to-Hip or Waist-to-Height Ratio: Going a step further, you can calculate ratios that may be even better indicators for visceral fat. The waist-to-hip ratio (WHR) is your waist circumference divided by your hip circumference. Higher WHR (above 0.85 for women, 0.90 for men) typically indicates more fat centralized in the abdomen relative to the hips. Similarly, your waist-to-height ratio should ideally be less than 0.5. These ratios help account for different body sizes and builds, and a number above the recommended threshold suggests you’re carrying too much fat in your belly for your frame.
-
Body Weight and BMI: Regular scale weight and Body Mass Index (BMI) are crude measures, but they can provide context. If you have a BMI in the overweight or obese range, it’s likely you have higher visceral fat as well. It’s possible to have normal weight but high visceral fat, so BMI alone isn’t a perfect indicator. Still, if your weight has been climbing, especially in the midsection, it’s a sign to investigate further.
-
Home Body Composition Scale: These days, many people use body fat measurement tool devices at home to estimate body fat percentage. A body composition scale looks like a regular bathroom scale but sends a harmless electrical signal through your body to estimate body composition. The technology, bioelectrical impedance analysis (BIA), works by measuring how the signal passes through water versus fat in the body. Muscle and blood, which contain more water, conduct electricity well, whereas fat slows it down. By measuring the impedance, the scale’s algorithm estimates your total body fat percentage. Some advanced scales even claim to output a visceral fat rating. These gadgets are popular for tracking fitness progress. People searching for the best scale for weight loss or the best body fat analyzer often end up with one of these smart scales. They can instantly tell you your overall body fat percentage and sometimes muscle mass, bone mass, etc.
-
Skinfold Calipers: Another body fat testing method is using skinfold calipers at specific sites to estimate total body fat. This method measures subcutaneous fat thickness at various body sites and plugs those measurements into equations to estimate overall body fat percentage. Calipers are affordable and can be fairly consistent in the hands of a trained user. However, like scales, they only measure subcutaneous fat under the skin. They cannot reach visceral fat. You might track a reduction in skinfold measurements as you lose weight, which is great, but you won’t know directly from calipers how your visceral fat is changing.
-
Home Blood Pressure and Blood Sugar Monitoring: Though not a direct measurement of fat, keeping an eye on your blood pressure, fasting blood sugar, and triglyceride levels can give indirect clues about visceral fat’s impact. High visceral fat often shows up as high blood pressure, borderline high fasting glucose, or abnormal cholesterol/triglycerides. These are the components of metabolic syndrome. If you notice these creeping up, it could be related to excess visceral fat.
At home, you’ll be using proxy measures to measure visceral fat. Regularly measure your waist and perhaps calculate waist ratios. The key is not to obsess over a visceral fat number, but to use these tools to ensure you’re moving in a healthier direction.
DEXA: The Gold Standard for Body Fat Analysis
For the most precise assessment of body composition, nothing beats a clinical scan. One widely used option is a DEXA test for body fat analysis. DEXA stands for Dual-Energy X-ray Absorptiometry. It’s a medical imaging technology that uses very low-dose X-rays to differentiate between bone, lean tissue, and fat. Originally developed to measure bone density, DEXA scans have become the gold standard for body fat measurement because of their accuracy. A single body fat analysis with a DEXA scan can tell you exactly what percentage of your body is fat, how much is lean muscle, and even how fat is distributed across different regions. Many DEXA machines can specifically estimate visceral fat by analyzing the fat in the deep abdominal area.
Getting a DEXA scan is a straightforward procedure: you lie on a table while the machine’s scanning arm passes over your body for about 5-10 minutes. The scan is painless, and the radiation exposure is minimal. The result is a detailed report showing your body fat percentage, lean mass, bone density, and fat distribution. For example, the scan might report how many pounds of fat you have in your android vs. gynoid regions, which correlates with visceral vs. subcutaneous fat.
The accuracy of DEXA is excellent. It is typically within ~2% error for body fat percentage, far superior to home methods. This makes it an appealing option for athletes and anyone serious about tracking changes in their body composition. However, DEXA scans are not as readily accessible as stepping on a scale at home. They require visiting a clinic or facility that has the DEXA equipment. Additionally, they aren’t free. The DEXA scan price can be significant.
Because of the cost and logistics, you might not get a DEXA scan monthly or even frequently, but doing one every now and then can be immensely informative. It can validate whether your training or diet is leading to fat loss and muscle gain, and specifically whether visceral fat is being reduced. If you’re serious about knowing your exact fat makeup, seeking out a DEXA scan is worth it. Many fitness and wellness centers now offer DEXA scans as part of their services. For example, BOD is a brand that provides DEXA body composition scans in specific locations. Clients can get a detailed DEXA report to accurately assess their fitness and fat levels with medical-grade precision.
How to Lose Visceral Fat
If you’re wondering how to lose visceral fat, the answer lies in overall fat loss through focused lifestyle changes. The encouraging news is that visceral fat is usually the first fat your body burns as you improve your habits. Here are the most effective strategies:
-
Be Active and Exercise Regularly: Physical activity is the nemesis of visceral fat. Aim for at least 30 minutes of exercise most days of the week. Both cardio and strength training are important. Cardio burns calories and helps reduce overall body fat. High-Intensity Interval Training (HIIT), which alternates bursts of intense effort with short rest, is especially effective at targeting belly fat. Strength training is crucial, too. It builds muscle mass, which increases your resting metabolism so you burn more calories even at rest
-
Improve Your Diet: To lose that deep belly fat, focus on a healthy, well-balanced diet rich in whole foods. Emphasize lean proteins, plenty of vegetables and fruits, and high-fiber foods like whole grains. These keep you full and nourish your body. At the same time, cut back on added sugars, refined carbs, and heavily processed foods. Sugar-sweetened beverages are one of the first things to eliminate. They pack in calories and spike insulin, promoting visceral fat storage.
-
Prioritize Quality Sleep: Don’t underestimate the power of sleep in weight management. Consistently getting 7-8 hours of high-quality sleep per night supports visceral fat loss. Poor sleep affects hunger hormones, often making you hungrier and prone to cravings for high-calorie foods. It also leaves you too fatigued to exercise effectively and elevates cortisol levels. Aim to establish a regular sleep schedule and good sleep hygiene.
Over time, you’ll not only lose visceral fat but also likely lose subcutaneous fat, leading to an all-around leaner physique. And remember, every bit of visceral fat lost is an investment in a longer, healthier life.
Visceral fat is a key measurement of health for a reason. It has profound effects on your body’s well-being. Paying attention to your visceral fat levels gives you insight that the scale alone cannot. Your goal should be to cultivate a healthy body composition. This is the state in which your body can function optimally. In your health and fitness journey, keep visceral fat in mind as a critical metric. By keeping your visceral fat in check, you are taking control of one of the most important aspects of your health and fitness.
