Frequently Asked Questions
What is EER and how is it different from TDEE?
EER (Estimated Energy Requirement) is a formula developed by the Institute of Medicine, distinct from the more commonly-used Harris-Benedict or Mifflin-St Jeor plus activity-multiplier approach. Both aim to estimate the same thing, total daily calorie needs, using different underlying research and coefficients.
What do the physical activity (PA) coefficients represent?
The PA coefficient scales your energy requirement based on activity level, and differs slightly by sex since men and women showed different activity-related energy expenditure patterns in the research used to develop the formula.
Is EER accurate for pregnant or breastfeeding people?
The Institute of Medicine EER formulas include separate adjustments adding extra calories for pregnancy and breastfeeding, which are not included in this general calculator. Consult your doctor for pregnancy-specific calorie guidance.
Why is EER lower or higher than a BMR-based calculator I have used before?
Different formulas use different research populations and mathematical approaches, so it is normal for BMR-and-activity-multiplier methods and the EER formula to give results that differ by a few hundred calories for the same person.
