NUTR 120 Lecture Notes - Lecture 15: Resting Metabolic Rate, Calorimetry, Health Professional
Document Summary
Energy in energy out = energy balance. Tee = basal needs + activity + thermogenesis. Basal needs: amount of energy needed to sustain basic life processes which depend on body size, body mass, and age. Basal energy expenditure (bee): amount of energy needed to sustain basic life processes which depend on body size, body mass, and age. Basal metabolic rate (bmr): measurement of 02 consumed and c02 released at rest, generally carried out after waking but before rising. Methods to measure bmr: ventilated hood, human calorimetry, direct: heat produced by the body, indirect: 02 consumption and c02 release. 54. 4 x 0. 9 x 24 = 1178 kcal basal metabolism. All non-fat body components (muscles, bone, organs, fluid) The more lbm a person has the more energy they will burn (the more intake they require) As overall body fat increases, overall lbm also increases. Increase in skeletal muscles (to support extra weight) Increase in size of organs (git, heart)
