White adipose tissue (WAT) or white fat is one of the two types of adipose tissue found in mammals. The other kind of adipose tissue is brown adipose tissue. In healthy non-overweight humans white adipose tissue composes as much as 20% of the body weight in men and 25% of the body weight in women. Its cells contain a single large fat droplet which forces the nucleus to be squeezed into a thin rim at the periphery.
