Not all fat is the same. Two people with the same weight can have very different health profiles depending on where the fat sits. Medicine looks closely at visceral fat, the fat in the abdominal cavity.
What defines visceral fat
It lies between and around the organs, for example around liver, pancreas and gut. Fat tissue is not just a store: it produces messenger substances that influence inflammation, blood sugar metabolism and blood pressure. In studies, the more visceral fat, the higher the risk of fatty liver, type 2 diabetes, high blood pressure and cardiovascular disease. This is also called metabolic syndrome.
How to assess your situation
- Waist circumference: measured with a tape at the level of the navel, after breathing out. Increased risk according to the German Obesity Society: women from 88 cm, men from 102 cm.
- Waist-to-height ratio: a value from 0.5 is considered a hint of increased risk.
- Lab values: fasting blood sugar, HbA1c, blood lipids, liver values and uric acid complete the picture. We set no limits of our own and refer to the laboratory's reference ranges. More under laboratory diagnostics.
- Imaging: ultrasound, CT or MRI measure visceral fat more precisely but only make sense in a medical setting. Scales with body fat analysis (BIA) give a rough orientation.
What influences fat distribution
- Diet: a lot of sugar, fruit juice, alcohol and highly processed products.
- Lack of exercise: long sitting and little muscle work.
- Sleep and stress: chronic lack of sleep and long-term stress, see Stress and cortisol.
- Hormones: menopause, thyroid, insulin resistance, certain medications.
- Predisposition: distribution is largely inherited.
Reducing it in a healthy way: what works
- Exercise in daily life: daily steps, stairs, breaks from sitting.
- Strength and endurance: two strength sessions per week plus several endurance sessions. More muscle mass improves sugar metabolism; see Muscle building and health.
- Protein and fiber: protein at every meal, plenty of vegetables, legumes, whole grains.
- Reduce sugar and alcohol: especially liquid calories.
- Sleep and recovery: seven to nine hours, regular times, see Sleep & rhythm.
- Moderate deficit instead of crash diet: Rapid diets also cost muscle mass and often fail because of the yo-yo effect. Notes on the approach are in the article Losing weight in a healthy way and in nutrition counseling.
When medical evaluation is important
With rapid, unexplained weight gain, water retention, strong thirst, shortness of breath or tiredness, with known heart, kidney or metabolic diseases and with medication that affects weight, evaluation belongs first in medical hands. Eating disorders also call for professional treatment.

Frequently asked questions
What is the difference between visceral fat and subcutaneous fat?
Subcutaneous fat lies under the skin, visceral fat in the abdominal cavity between and around the organs, such as liver and gut. Visceral fat releases more messenger substances that influence inflammation and sugar metabolism. It is therefore more relevant to health than the same amount of fat on hips or thighs.
How do I know whether I have too much belly fat?
A simple hint is waist circumference, measured at the level of the navel. According to the German Obesity Society, risk is increased from 88 cm in women and 102 cm in men. The ratio of waist circumference to height (from 0.5) is also used. More precise methods are ultrasound, CT or MRI.
Can I lose fat specifically on the belly?
No, fat cannot be reduced at a single spot on purpose. Visceral fat, however, often responds well to regular exercise, strength and endurance training and a balanced diet overall, sometimes even before body weight changes noticeably.
Do hormones and stress play a role?
Yes. Chronic stress, lack of sleep, alcohol and hormonal changes such as menopause or an underactive thyroid can influence fat distribution. With conspicuous weight gain, a medical evaluation is therefore part of the process.
Do detox programs or fasting weeks reduce belly fat?
Short-term programs usually bring only temporary changes in weight. What matters is what can be maintained in daily life. Time-limited fasting can be one building block but should be discussed with a doctor beforehand if you have illnesses or take medication.
