How San Francisco BMR Calculator Works
The technical expertise behind this tool relies on the Mifflin St Jeor equation, which is currently the gold standard for metabolic estimation. In my years of coding mathematical models, I have found that this formula provides the most reliable results for a modern lifestyle. The logic calculates the energy your body needs to maintain vital functions like breathing, circulation, and cell production.
The calculation method determines your base rate and then applies a multiplier based on your physical activity level. The formula looks like this:
(Where s is +5 for males and -161 for females).
I have ensured that our accuracy explanation is transparent; while no tool replaces a lab test, this is the most accurate estimation available. Our data handling note is simple: the calculation happens locally, keeping your weight and age private while providing expert insights.
