![]() ![]() Because TEF is so difficult to calculate it is commonly assumed to be a multiple of the number of calories consumed or amount of calories expended (BMR). One helpful piece of information about TEF is that Protein has more than double the TEF of Carbohydrates and Fat. Since every food has a different TEF, calculating TEF becomes very complicated. TEF also known as Dietary Induced Thermogenesis (DIT) or Specific Dynamic Action (SDA) is the amount of energy expenditure above your BMR due to your body processing and storing food. Normal-weight ( n 264) and obese ( n 234) individuals were studied and REE was measured by indirect calorimetry. A predictive equation for resting energy expenditure (REE) was derived from data from 498 healthy subjects, including females (n 247) and males (n 251), aged 19-78 y (45 +/- 14 y, mean +/- SD). A predictive equation for resting energy expenditure (REE) was derived from data from 498 healthy subjects, including females ( n 247) and males ( n 251), aged 1978 y (45 ± 14 y, x ± SD). For the above TDEE equation, the multiple PAL takes into account your TEF as well. American Journal of Clinical Nutrition 1990 Februrary. Jeor equation for healthy people: Mifflin St. Modified Penn State equation that uses Mifflin St. Your PAL can range from very low for a sedentary life to very high for an Olympic swimmer. T he calculated difference between each predicted energy expenditure equation and the actual measured energy expenditure. The Above TDEE equation calculates TDEE using a multiplication factor for the PAL. This calorie calculator is based upon the Mifflin-St Jeor Equation for calculating ones basal metabolic rate (BMR): For men: BMR 10W + 6.25H - 5A + 5 For. We have already discussed how BMR is the amount of energy in Kilocalories that your body uses while at rest. Your TDEE is made up of three parts your BMR, PAL, and Thermic Effect of Food (TEF).
