Visceral fat — the fat deposited within the abdominal cavity around organs — is metabolically distinct from subcutaneous fat. It contains a higher proportion of large, inflamed adipocytes, a greater density of immune cells, and directly drains into the portal vein, delivering its secretions directly to the liver. A person with normal BMI can carry pathological amounts of visceral fat — an underdiagnosed condition called TOFI (Thin Outside, Fat Inside).
A normal BMI with high waist circumference is a risk profile that conventional medicine consistently underestimates.
Reducing Visceral Fat
- Aerobic exercise — reduces visceral fat more selectively than subcutaneous fat
- Caloric deficit — visceral fat responds faster to energy restriction than subcutaneous fat
- Reducing ultra-processed foods and added sugars — fructose is preferentially converted to hepatic and visceral fat
- Sleep — visceral fat accumulation is accelerated by sleep restriction independent of caloric intake
- Strength training — increases insulin sensitivity and resting metabolic rate
