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. Various scientists have derived many formulas and equations to find the RMR. 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. RMR is the amount of calories that is burned while in complete rest. For the above TDEE equation, the multiple PAL takes into account your TEF as well. Women: (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) - 161. All equations underestimate REE: HarrisBenedict, mean difference 648 kcal (limits of agreement +627 to 1923 kcal) MifflinSt.Jeor, mean difference 694 kcal (limits of agreement +544 to 193 kcal) Schofield, mean difference 531 kcal (limits of agreement +662 to 1723 kcal) and IretonJones, mean difference 556 kcal (limits of agreement +7. Your PAL can range from very low for a sedentary life to very high for an Olympic swimmer. Mifflin-St Jeor Equation The equations for males and females are: Men: (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) + 5. The Above TDEE equation calculates TDEE using a multiplication factor for the PAL. We have already discussed how BMR is the amount of energy in Kilocalories that your body uses while at rest. Harris-Benedict - historically, this is the most notable BMR formula and was created in 1919. To use it, you need to know the following variables: sex, age, height, and weight. ![]() Your TDEE is made up of three parts your BMR, PAL, and Thermic Effect of Food (TEF). You can choose from the 5 most popular equations: Mifflin-St Jeor - one of the most popular BMR equations recommended by US Academy of Nutrition and Dietetics. ![]() Understanding Your Total Daily Energy Expenditure
