Document Summary
Review for exam 3 - posted on blackboard. Body mass index (bmi) - the current standard for assessing the healthfulness of body weight. Body composition - the relative proportions of fat and lean tissue that make up the body. Subcutaneous fat- (located under the skin) does not increase health risk: fat around the thighs and lower body is subcutaneous. Visceral fat - (located around the organs in the abdominal area) does increase health risk. Basal metabolic rate - rate of energy use at rest (and fasting) Thermic effect of food - the energy used to digest food, and absorb, metabolize and store nutrients: tef is estimated at about 10% of total energy expenditure. Leptin - protein made by fat cells that decreases appetite and increases energy expenditure. Ghrelin - protein made by stomach cells that enhances appetite and decreases energy expenditure. Appetite- desire to consume specific foods triggered by external cues (for example, smell) independent of hunger.
