Parameters

Basal Metabolic Rate (BMR) Result

Formula

Male BMR = 88.362 + (13.397 × W) + (4.799 × H) - (5.677 × Age)
Female BMR = 447.593 + (9.247 × W) + (3.098 × H) - (4.330 × Age)
Where W is in kg and H is in cm.

Clinical Pearls

Provides a baseline for calculating nutritional requirements, especially for parenteral or enteral feeding regimens, or for prescribing weight-loss diets.

Limitations

Equations often overestimate BMR in obese individuals and underestimate in very muscular individuals.
