Mifflin-St Jeor Equation for RMR

Calculate resting metabolic rate (RMR) using Mifflin-St Jeor equation. Male: 10xW + 6.25xH - 5xA + 5. Female: 10xW + 6.25xH - 5xA - 161. More accurate than Harris-Benedict in non-obese adults.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Calculate resting metabolic rate (RMR) using Mifflin-St Jeor equation. Male: 10xW + 6.25xH - 5xA + 5. Female: 10xW + 6.25xH - 5xA - 161. More accurate than Harris-Benedict in non-obese adults

Each component has a specific meaning:

  • Mifflin-St Jeor equation — The mifflin-st jeor equation recorded for the scenario being assessed.

Note: Interpret the mifflin-st jeor rmr result against the thresholds and context described above.

How to Use

Enter the Mifflin-St Jeor equation for the scenario you are assessing. Calculate resting metabolic rate (RMR) using Mifflin-St Jeor equation. Male: 10xW + 6.25xH - 5xA + 5. Female: 10xW + 6.25xH - 5xA - 161. More accurate than Harris-Benedict in non-obese adults. Use the mifflin-st jeor rmr result to inform your calculation.
