Visceral fat is the fat stored deep inside your abdomen, wrapped around organs such as your liver and intestines. Unlike the fat you can pinch under your skin, visceral fat has links to heart disease, type 2 diabetes, and high cholesterol. A body composition Smart Scale such as the RENPHO MorphoScan Nova estimates your visceral fat and reports it as a Visceral Fat Grade — a number that is most useful for watching your trend over weeks and months.
What is visceral fat?
Visceral fat is body fat stored inside the abdominal cavity. Cleveland Clinic describes it as fat that "lines your abdominal walls and wraps around many of your internal organs".
Your body stores fat in two main places:
-
Subcutaneous fat sits directly under your skin — the soft fat you can pinch on your arms, thighs, and belly.
-
Visceral fat sits deeper, behind your abdominal muscles and around your organs. You cannot pinch visceral fat, and you cannot always see it — someone with a normal-looking frame can still carry a high amount.
Why visceral fat matters for your health
Visceral fat carries more health risk than fat stored elsewhere. Cleveland Clinic also links excess visceral fat to atherosclerosis and metabolic syndrome.
Hidden body fat is also why weight alone can mislead. Research on "normal weight obesity" found that people with a healthy BMI but high body fat had a higher rate of metabolic syndrome — 16.6% compared with 4.8% in people with low body fat. A scale that only shows weight will miss that risk entirely.
How is visceral fat measured?
Imaging measures visceral fat most precisely. CT and MRI scans are the reference standards, and DXA scans estimate visceral fat closely against CT. CT, MRI, and DXA scans are accurate but expensive, and you cannot repeat them every week.
Here is how the main measurement methods compare:

Measuring your waist
The National Heart, Lung, and Blood Institute uses waist circumference as a marker of abdominal fat. An unhealthy waist circumference is greater than 40 inches for men and greater than 35 inches for women. Measure just above your hip bones, after breathing out, with the tape snug but not compressing your skin.
The RENPHO Smart Tape Measure+ makes that check easy to repeat. Its Easy-Lock Hook holds the tape in place, so you can measure your waist on your own. Each reading syncs to the RENPHO Health App — the same App your Smart Scale uses — so your waist trend and your Visceral Fat Grade live in one place.
How a RENPHO scale reports visceral fat
A RENPHO body composition smart scale estimates visceral fat using bioelectrical impedance analysis — it sends a small electrical current through your body and measures how easily the current travels. Fat conducts electricity differently from muscle and water, so the RENPHO Health App can estimate your body composition and report a Visceral Fat Grade.
The Visceral Fat Grade is an estimate, not a direct measurement, so the most useful way to read it is as a trend. A grade that falls steadily over several months means your habits are working, even if your weight moves slowly.
Electrode count matters here. An 8-electrode scale gives the estimate more to work with. The RENPHO MorphoScan Nova adds four electrodes in a handle, so the current passes through your arms and torso as well as your legs. Read how MorphoScan Nova compares with a DEXA scan to see how close a home reading gets to a clinical one.
To read your grade, start with the ranges in the RENPHO Health App: Average at 0–9, Slightly High at 9–14, and High at 14 and above. Watch which way your grade moves, because a climbing grade is your cue to adjust your habits.
The App's visceral fat tips point to three moves: eat a balanced diet of lean proteins, whole grains, low-fat dairy, fruits, and vegetables; cut back on prolonged sitting; and add more aerobic training. Research backs aerobic training most strongly, and the next section shows why.
What reduces visceral fat?
Exercise is one of the best-supported ways to reduce visceral fat, and the type of exercise matters.
-
Aerobic exercise has the strongest evidence. A meta-analysis of 15 studies and 852 participants found that moderate- or high-intensity aerobic training has the greatest potential to reduce visceral fat, while low-intensity training showed no significant effect.
-
Resistance training alone showed no significant effect. A review of 35 randomized trials that measured visceral fat with CT or MRI found a significant reduction with aerobic exercise, and no significant reduction with resistance training alone. Strength work still earns its place, because it protects muscle while you lose fat.
-
Meet the baseline guidelines. The CDC recommends at least 150 minutes of moderate-intensity activity a week, plus muscle-strengthening activity on at least 2 days.
Pairing aerobic and strength training — cardio for visceral fat, strength for muscle — is exactly the approach behind body recomposition.
How to track visceral fat at home
-
Weigh in at the same time each day. Hydration shifts every reading, so morning weigh-ins before eating or drinking give the most consistent results.
-
Watch the weekly trend. A single Visceral Fat Grade can move with water and food. A steady drop over four to eight weeks is the real signal.
-
Pair the scale with the RENPHO Smart Tape Measure+. Waist circumference and Visceral Fat Grade falling together is strong confirmation that abdominal fat is coming down. Because the tape syncs to the same App as your scale, you can check both trends in one place.
-
Track muscle at the same time. Losing visceral fat while keeping muscle mass steady is the best outcome — and a RENPHO body composition Smart Scale reports both.
The bottom line
Visceral fat is the fat you cannot see and cannot pinch, and it carries more health risk than the fat you can. You do not need a CT scan to keep an eye on it — a waist measurement from the RENPHO Smart Tape Measure+ and a body composition Smart Scale such as the RENPHO MorphoScan Nova give you a practical way to watch your visceral fat trend at home. Pair regular aerobic exercise with strength training, weigh in consistently, and let the trend show you what the number on a standard scale never could.

Frequently asked questions
What is a healthy visceral fat level?
In the RENPHO Health App, a Visceral Fat Grade of 0–9 is Average, 9–14 is Slightly High, and 14 and above is High. Each brand grades visceral fat on its own system, so judge your own trend rather than comparing your number with another brand's scale. For a second marker, the NHLBI's waist thresholds — over 40 inches for men and over 35 inches for women — are a widely used marker of unhealthy abdominal fat.
Can a Smart Scale measure visceral fat?
A body composition Smart Scale estimates visceral fat using bioelectrical impedance rather than measuring it directly. CT and MRI scans are the reference standards, so a scale reading is best used to track your trend over time.
What is the fastest way to lose visceral fat?
Research points to moderate- or high-intensity aerobic exercise as the most effective single approach. A 2013 meta-analysis found low-intensity exercise had no significant effect on visceral fat.
Can you be thin and have high visceral fat?
Yes. People with a normal BMI can still carry high body fat, and research on "normal weight obesity" links that pattern to a higher rate of metabolic syndrome.
Why does my visceral fat reading change from day to day?
Hydration, meals, and exercise all change how a bioelectrical impedance scale reads your body. Weighing at the same time each day and comparing weekly averages gives the most reliable picture.
