Overview

Visceral fat, also known as organ fat, is located inside the peritoneal cavity, packed in between internal organs, as opposed to subcutaneous fat which is found underneath the skin and intramuscular fat which is found interspersed in skeletal muscle. An excess of visceral fat leads to the "pot belly" or "beer belly" effect, in which the abdomen protrudes excessively. This body type is also known as "apple" shaped, as opposed to "pear" shape, in which fat is deposited on the hips and buttocks. Visceral fat is composed of several adipose depots including mesenteric, epididymal white adipose tissue (EWAT) and perirenal depots. Visceral fat accumulation is associated with increased risk of heart disease and type 2 diabetes.
