Resting Energy Expenditure (REE) Recommended Formulas
Resting Energy Expenditure (REE), also referred to as Resting Metabolic Rate (RMR) is defined as the amount of calories expended at rest. While there are many methods to calculate REE, we recommend using the Mifflin St. Jeor Equation. See below for references, guidance on how to properly apply the Mifflin St. Jeor Equation, and the truth behind common misuses of this equation.
The Mifflin St. Jeor Equation (MJSE)
The Recommended, Evidence-Based Method for Estimating Resting Energy Expenditure (REE)
The Mifflin St. Jeor Equation (MSJE) was created by Dr. Sachiko St. Jeor, President of Genquest Nutrition Solutions, and her medical student, Dr. Mark Mifflin (see Reference 1,2 in link below). In 2005, the MSJEwas designated by the Academy of Nutrition and Dietetics as the evidence-based standard predictive equation for REE. Explore the links below to see sample calculations of REE using the MSJE, a list of references for the equation, and a comparison of the Mifflin St. Jeor Equation (1990) versus the Harris-Benedict Equation (1919).       The Formula

MALE 10 x wt (kg) + 6.25 x ht (cm) - 5 x age (y) + 5 FEMALE 10 x wt (kg) + 6.25 x ht (cm) - 5 x age (y) - 161 TRANSGENDER 10 x wt (kg) + 6.25 x ht (cm) - 5 x age (y) - 78* * Katz/Aronson, Diet ID: -78 is the mean (average) of the male and female factors using the MSJE. The transgender population needs further study. We recommend additional measures of body composition (lean body mass and body fat percentage) waist circumference and grip strength for comparison.
