In-Depth Guide & Mathematical Methodology

🧪 Comparison of Clinical BMR Formulas

Mifflin-St Jeor (1990): Recommended by the Academy of Nutrition and Dietetics as the most accurate formula for the general population (±10% error margin).

Katch-McArdle (1996): Most accurate for athletes because it calculates metabolic rate directly from Lean Body Mass (LBM).

Harris-Benedict (1984): The historical clinical standard, slightly overestimates calories in overweight individuals.
