The major portion of the fat is stored just under the skin. Fat also surrounds important organs like the kidneys, liver and the heart. Fat also gets deposited on the top and beneath the muscles in the human body. For males the fat gets deposited in the chest, buttocks and abdomen and in women the fat tends to gather in the breasts, buttocks, waist and hips. Testosterone and estrogen, the two sex hormones, determine the position of deposition. Fat is technically known as adipose tissue which is composed of cells called adipocytes. A fat cell looks like a tiny bag containing very small quantity of fat. In earlier days adipocytes or fat cells were considered to be storing extra calories only. There are two types of adipose (fat) tissue. White adipose tissues are also known as WAT and brown adipose tissues also commonly known as BAT.
