Basal Metabolic Rate Calculator
Determine your foundational resting energy overhead and daily active expenditure limits.
What is BMR & How is it calculated?
The Basal Metabolic Rate (BMR) represents the absolute minimum quantity of caloric energy required to keep your body functioning in a complete vegetative resting state. This energy fuels automated internal procedures like cellular synthesis, homeostasis, neurological processing, and circulatory maintenance.
The Scientific Framework: This calculation dynamically processes your physiological mass, height structural dimensions, gender variable bias, and age timeline using the audited Mifflin-St Jeor Equation, recognized by clinical researchers as the modern benchmark for accuracy.
Men: BMR = 10W + 6.25H - 5A + 5
Configured for Metric Scaling. W = weight (kg), H = height (cm), A = age (years).
