The body is
composed of fat and fat-free components, such as muscle, bone,
and water. Each component plays a critical role in the health of
the body. Fat Mass (FM) is the total amount of fat in the body.
The ideal amount of fat for minimal disease risk is 23%-31% of
total body weight in women.
consists of the following types of fat:
Subcutaneous Fat, also called Subcutaneous Adipose Tissue
(SAT), is located directly beneath the skin. Subcutaneous fat
serves as insulation against outside cold.
also called Visceral Adipose Tissue (VAT), is located deeper
within the body. Visceral fat serves as a cushion between
organs. Omental and mesenteric fat (in the abdomen) are
examples of visceral fat.
Fat-Free Mass (FFM),
also called Lean Body Mass (LBM), is the total amount of nonfat
(lean) parts of the body. It consists of approximately 73%
water, 20% protein, 6% minerals, and 1% ash.
