Subcutaneous vs visceral fat. Cross-section of the abdomen: subcutaneous fat sits under the skin; visceral fat surrounds organs and is more strongly linked to cardiometabolic risk.

Location over amount

Visceral fat, measured by CT or MRI, is an independent risk marker for cardiovascular and metabolic disease and death, and fat in the liver and around the heart may add to that risk [1].

Waist circumference is a simple proxy you can track at home [1]. Exercise and weight loss reduce visceral fat; in the Diabetes Prevention Program, a lifestyle program targeting 7% weight loss and 150 minutes of activity a week cut diabetes incidence by 58% [2].
