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 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.
