Many people assume that a normal body weight means low abdominal-fat risk. In practice, that is not always true. A person may look slim overall but still have a growing waistline and rising visceral fat around the organs.

This article explains the difference between visceral fat and subcutaneous fat, why visceral fat matters more than many people realise, and how TCM interprets common underlying constitutional patterns.

Important: If you already have raised fasting glucose, abnormal lipids, fatty liver, early cardiovascular disease in the family, or unexplained weight loss, arrange Western medical assessment first.

A normal BMI does not guarantee a safe waistline

BMI reflects only the overall relationship between height and weight. It does not show where fat is stored. Two people with the same BMI can have very different waistlines and metabolic risks.

For Chinese adults, a waist circumference of 90 cm or above in men and 80 cm or above in women is already considered abdominal obesity and deserves attention, even if total body weight still looks “normal”.

Visceral fat versus subcutaneous fat

Category	Subcutaneous fat	Visceral fat
Location	Under the skin	Around the liver, stomach and intestines
Feel	Can usually be pinched	Cannot be directly pinched
Metabolic activity	Lower	Higher
Health risk	Relatively lower	More closely linked to fatty liver, diabetes and cardiovascular disease

Visceral fat is the more important metabolic risk, because it actively affects inflammation and insulin sensitivity.

How TCM looks at a slim person with a belly

TCM does not judge only by “fat” or “thin”. Common constitutional patterns include:

Constitution	Common features	Main direction
Phlegm-damp	Heaviness, thick tongue coating, sticky mouth, soft central belly	Strengthen spleen, resolve phlegm
Liver stagnation	Stress eating, bloating, emotional swings	Soothe liver qi
Spleen deficiency	Fatigue, weak appetite, bloating after meals	Strengthen spleen qi
Kidney deficiency	Feeling cold, night urination, low back weakness	Support spleen and kidney

Many people show a mixed pattern rather than a single textbook type.

Why visceral fat is more dangerous

Visceral fat is metabolically active. It releases inflammatory mediators, worsens insulin resistance and increases the liver’s burden. That is why a slim-looking person can still face:

• Fatty liver
• Rising fasting glucose
• Higher triglycerides
• Higher blood pressure
• Increasing waistline despite relatively stable weight

Who is more likely to develop it

• People with sedentary work
• Those with chronic sleep shortage
• High-stress individuals with binge eating
• People who drink alcohol frequently
• Post-menopausal women
• Those with a family history of diabetes or cardiovascular disease

Four things to start doing

1. Measure your waist regularly, not just your weight.
2. Cut back on sugary drinks and refined sugar.
3. Add resistance training two to three times per week.
4. Aim for at least seven hours of sleep.

How Aspira TCM Clinic assesses this

Dr Au reviews waist and body composition, diet pattern, alcohol intake, bowel habits, sleep, stress and (for women) menstrual history. If there is concern about fatty liver, abnormal glucose or lipid markers, Western medical checks are recommended first.

FAQ

If my body-fat scale shows visceral fat 12, is that high?

Home scales are only rough estimates, but if the reading stays high and your waistline is above the cut-off, proper blood tests and clinical assessment are worthwhile.

Is a slim person’s belly just due to weak abdominal muscles?

Abdominal strength matters, but the more common reasons are fat distribution, prolonged sitting, stress, poor sleep and long-term dietary patterns.

Can acupuncture directly reduce visceral fat?

Acupuncture may help as part of a broader programme by improving sleep, appetite regulation and constitution, but it does not replace dietary and lifestyle change.

Can I see a TCM doctor while taking lipid-lowering medication?

Yes, but do not stop or reduce medication on your own. TCM may be used as supportive care alongside proper medical monitoring.
