Visceral vs. subcutaneous fat: why location matters
Not all body fat carries the same health risk. Where it's stored changes the metabolic picture significantly.
Subcutaneous fat sits just beneath the skin and is the fat most people can pinch — it carries comparatively lower metabolic risk and, in some research, may even have a mildly protective metabolic role in certain amounts.
Visceral fat, by contrast, surrounds internal organs deep in the abdominal cavity and is metabolically active in a less favorable way — it releases inflammatory compounds and free fatty acids directly into circulation near the liver, which is strongly linked to insulin resistance, type 2 diabetes risk, and cardiovascular disease.
Waist circumference is a more practical proxy for visceral fat than total body weight or BMI, since two people with identical weight and height can carry very different amounts of visceral versus subcutaneous fat.
Aerobic exercise appears to preferentially reduce visceral fat even before major changes show up on the scale, which is one reason waist circumference sometimes improves noticeably before overall body weight does in early stages of a new exercise routine.
