Visceral fat is also known as abdominal fat, organ fat or intra-abdominal fat. It is located inside the abdominal cavity, packed in between organs such as the stomach, liver, intestines, or kidneys. Visceral fat is different from subcutaneous fat (underneath the skin) and intramuscular fat (interspersed in skeletal muscles). Fat in the lower body, as in thighs and buttocks, is subcutaneous, whereas fat in the abdomen is mostly visceral. Visceral fat is likely to cause visceral fat syndrome or other lifestyle-related diseases. Men or post-menopausal women are more prone to accumulation of visceral fat.
