Body composition

Body composition refers to the make up of:

• lean tissue (muscle)
• and fat tissue

in the body.

Lean tissue is composed of:

• muscle,
• bone
• and organs.

Fat tissue is composed of three different categories::

• essential fat,
• storage fat
• and non-essential fat.

Essential and storage fat are both necessary for the body to function, while non-essential fat serves no real purpose.

• See BMI. Most runway models meet the Body Mass Index (BMI) physical criteria for anorexia.
