Document Summary

Body mass index (bmi) = kg/m^2 index of total body weight independent of height: doesn"t indicate how much body weight is fat, doesn"t indicate location of body fat, healthy: 18. 5-24. 9. Healthy body weight nutritional assessment: anthropometric physical body, biochemical blood & tissue, clinical blood pressure, dietary nutrients. Measures of body composition: underwater weighing (hydrodensitometry, calipers, bioelectrical impedance analysis (bia, near infrared reactance, isotope dilution, dexa. Measures of fat distribution: waist circumference, waist to hip ratio (man and women: apple and pear) Energy output: bmr, pa, tef (thermic effect of food) 3500 kcal = (1 lb) of body fat. Hunger: inborn instinct, internal signal from hypothalamus releasing hormone. Hunger, satiation, and satiety: physiological influences, sensory influences, cognitive influences, post-ingestive influences, post-absorptive influences. Factors affecting bmr: age, growth, size (height and weight, body composition (proportion of lean tissue, physiological state (e. g. fever and temp in environment) Physical activity fitt principle frequency, intensity, time, type.
