The REE is useful to prevent under and overfeeding of individuals,Įspecially in the acute care hospital setting. These measurementsĪre printed out by the metabolic cart after completion of the indirectīenefits of using REE in the clinical setting Used to calculate the 24-hour energy expenditure. The amount of oxygen consumed by the individual. The RQ represents the ratio of carbon dioxide exhaled to With these measurements the resting energy expenditure (REE) and respiratory quotient (RQ) can be calculated. €“ all computed to represent values corresponding to 1 minute time intervals. (i.e., oxygen uptake VO2) and the amount of carbon dioxide,Īs a by-product of metabolism, expelled to atmosphere (CO2 output – VCO2) Passing through the lungs, the amount of oxygen extracted from it EnergyĮxpenditure can be measured indirectly with a metabolic cart byĪnalysis of respired gases (usually expired) to derive volume of air This is expensive and very impractical in the clinical setting. Well as chronic illness feeding regimens.Įnergy expenditure can be measured directly by putting a person in aĬalorimeter and measuring the amount of heat produced by the body mass. Programs for specific individuals for weight loss purposes or acute as These equations have limited clinical value when tailoring nutrition (3) There is a large variation between individuals, whenĬomparing their measured energy expenditure to the calculated amount. The Harris-Benedict equations have been found to overestimate by 6% toġ5% the actual energy expenditure measurements done by indirectĬalorimetry. Weight in kilograms, height in centimeters, age in years Harris-Benedict Equations (calories/day): However, these formulas are skewed towards young and non-obese Were established in 1919 and took into account gender, age, height and Predicted energy expenditure are the Harris-Benedict equations. (5) One of the most frequently used formulas for Nearly 200 published energy expenditure formulas dealing with variousĬonditions, disease states, age, presence of obesity and otherĪdditional factors. EnergyĮxpenditure can be estimated by numerous published formulas. Resting energy expenditure represents the amount of calories requiredįor a 24-hour period by the body during a non-active period. The last option, use metric, you want to select no for USA measurements or your TDEE will be too high.Resting Energy Expenditure "REE" ©1998 VacuMed Whenever the energy expenditure information changes: age, weight, and/or activity level, you would need to recalculate your TDEE. Very Active = BMR * 1.725 (hard exercise/sports 6-7 days/wk)Įxtremely Active = BMR * 1.9 (hard daily exercise/sports & physical job or 2X day training)īMR Formula for Men = 66 + (13.7 * wt in kg) + (5 * ht in cm) – (6.8 * age in years)īMR Formula for Women = 655 + (9.6 * wt kilos) + (1.8 * ht in cm) – (4.7 * age in years) Moderately Active = BMR * 1.55 (moderate exercise/sports 3-5 days/wk) Lightly Active = BMR * 1.375 (light exercise/sports 1-3 days/wk) Sedentary = BMR * 1.2 (little or no exercise, desk job) TDEE Calculator with macro breakout Guide to the Daily Calorie Requirements Calculator Contact me for more details on the protocol to increase nutrition, proper macro percentages, and how manipulate body weight based on activity levels. If you find that you aren’t eating at the level the calculator returns, you might need to increase intake, SLOWLY!! Doing so will make you feel better overall.
