Document Summary

Body composition: (2-component model) amt of fat and fat-free mass (ffm) that composes the body (does not take into account age, sex, race) Fat-free mass: primarily bone, muscle, vital organs and connective tissue. 4-component model takes into account fat, protein, minerals and h2o (more accurate at predicting % body fat. Essential fat: fat required for normal physiological functioning. Functions like: structural components of cell membrane, synthesis of certain hormones, transport of fat-soluble vitamins. Storage fat: fat stored in adipose tissue for energy supply. Located underneath skin, in abdominal cavity, around certain organs. Taller, heavier, larger muscle mass, lower total body fat content. Excess fat deposited on upper torso and around the. Has sex specific fat deposits: breasts, pelvic/thigh regions, other areas. Excess fat deposited below waist thighs, hips and butt abdomen. Weight gain/obesity: occurs when energy intake exceeds energy expenditure.
