HNF150 SPRING 2014 Prof Alaimo Lecture Notes ENERGY BALANCE I What is Energy Balance A Energy Balance E intake E expenditure Measured in Kcal B Methods to measure Energy intake 2 calorimeter add up all the calorie content in food food composition tables add up kcal value all food and drink consumed C Components of Energy expenditure 3 basal metabolic rate sum total of all involuntary activities necessary for life except digestion and voluntary activities thermic effect of food increase in BMR due to eating voluntary activities intentional activities such as walking sitting biking D Determinants of Basal Metabolic Rate 9 controlled by hormone produced by the thyroid gland thyroxine age height growth body composition fever stress environmental temp fastingstarvation malnutrition I Measuring Total Energy Expenditure use formulas for approximate estimates Formulas based on gender BMR activity level OR the sum of minutes of each activity x kcals expended by that activity lab assessments pedometers accelerometers and more Ill Body Mass Index BMI A Formulas BMI weight kgheight m2 BMI weight lbheight in 2 x 705 B Problems with BMI as a measure of body fatness athletes have a lot more muscle so that can be shown up as fat not very accurate HNF150 SPRING 2014 Prof Alaimo Lecture Notes IV Methods of Assessing Body Fatness A Fatfold Measures uses skinfold caliper B Dual

Determinants of Eating Behavior quotGoquot Mechanisms stimulate eating 0 Hunger physiological need to eat 0 Appetite psychological desire to eat quotStopquot Mechanisms signal the body to stop eating 0 Satiation perception of fullness that builds throughout a meal determines amount of food consumed at a meal 0 Satiety perception of fullness that lingers in the hours after a meal inhibits eating until the next meal time determines length of time between meals HNF150 Prof Alaimo SPRING 2014 Lecture Notes A What Determines quotGoquot Eating Behavior 1 Hunger O O regulated by the hypothalamus in the brain Hunger is also regulated by nutrients present in the blood size and composition of previous meal eating habits weather exercise habits sex hormones physical and mental disease adaptation of stomach to meal sizes 2 Appetite is a learned behavior 0 000000 learned preferences aversions and timings brain compounds endorphins serotonin some diseases and drugs affect taste and food intake inborn preferences for fat salt sweet environmental conditions social interactions stress B What Determines Stop Eating Behavior 1 Satiation hypothalamus receives signals nerves and hormones from 3 0 presence of food in upper GI tract stomach expands o nutrients in the small intestine 0 absorption of nutrients into the bloodstream 2 Satiety 2 suppresses hunger 46 hours after meal 0 may be
