One key difference between these two sets of equations is that the equations for weight maintenance do not include a growth component. A set of equations (for boys and girls) who are in a weight maintenance situation (equations estimate TEE-BEE plus other energy consuming processes and activities not counting growth).A set of equations (for boys and girls) who are not in a situation for weight loss or weight maintenance (equations estimate BEE-the basic energy cost of living for a 24 hour period).Total Energy Expenditure (TEE) is the sum of BEE (which includes a small component associated with arousal, as compared to sleeping), thermic effect of food, physical activity, thermoregulation, and the energy expended in depositing new tissues and in producing milk.Įquations to Estimate Energy Expenditure in Overweight and Obese Children and Adolescents (3-18 years)īased on analysis of the data from several research efforts, the authors of the IOM report provide two sets of predictive equations for estimating TEE in overweight and obese youth (ages 3-18) ( overweight defined in the IOM report as BMI>=85% for age and sex): Resting metabolic rate (RMR) is the energy expenditure under resting conditions, tends to be somewhat higher (10 to 20 percent) than under basal conditions due to increases in energy expenditure caused by recent food intake (i.e., by the “thermic effect of food”) or by the delayed effect of recently completed physical activity The BMR reflects the energy needed to sustain the metabolic activities of cells and tissues, plus the energy needed to maintain blood circulation, respiration, and gastrointestinal and renal processing (i.e., the basal cost of living).īasal energy expenditure (BEE) is determined by extrapolating BMR to 24 hours, expressed as kcal/24 h. The report identifies different measurements of energy needs:īasal metabolic rate (BMR) corresponds to the situation in which food and physical activity have minimal influence on metabolism. In 2005, the US Institutes of Medicine released Dietary Reference Intakes for Energy, Carbohydrate, Fiber, Fat, Fatty Acids, Cholesterol, Protein, and Amino Acids (Macronutrients).Īs part of this effort, the entitles responsible for creating the Dietary Reference Intakes (Panel on Macronutrients, Subcommittees on Upper Reference Levels of Nutrients and Interpretation and Uses of Dietary Reference Intakes, and the Standing Committee on the Scientific Evaluation of Dietary Reference Intakes) developed equations for estimating total energy expenditure (TEE) for different populations based on research and data from the doubly labeled water (DLW) method of measuring total energy expenditure. PA = 1.60 if PAL is estimated to be ≥ 1.9 PA = 1.35 if PAL is estimated to be ≥ 1.6 PA = 1.18 if PAL is estimated to be ≥ 1.4 PA = 1.45 if PAL is estimated to be ≥ 1.9 PA = 1.24 if PAL is estimated to be ≥ 1.6 PA = 1.12 if PAL is estimated to be ≥ 1.4 PA = 1.00 if PAL is estimated to be ≥ 1.0 Where PA is the physical activity coefficient: How much physical activity do children need?
