HOW DO NUTRITIONISTS MEASURE TOTAL ENERGY EXPENDITURE?
HOW DO NUTRITIONISTS MEASURE TOTAL ENERGY EXPENDITURE? Energy must be supplied regularly to meet needs for the body’s survival. Although all energy eventually takes the form of heat. Knowing these facts can help us in the measurement of total energy expenditure. To measure total energy expenditure, we need learn more about energy requirements ENERGY REQUIREMENTS Energy requirements are the dietary energy intake that is required for growth or maintenance and physical activity. In children and pregnant or lactating women, energy requirements include the needs associated with the deposition of tissues or the secretion of milk. In ill or injured people, the stressors have an effect by increasing or decreasing energy expenditure. COMPONENTS OF ENERGY EXPENDITURE We divide the TEE into three parts. Energy is expended by the human body in the form of basal energy expenditure (BEE), thermic effect of food (TEF), and activity thermogenesis (AT). These three components make up
