Medical Disclaimer: This calculator uses the Mifflin-St Jeor Equation, which is considered the most accurate BMR formula for most adults. BMR represents the calories needed for basic physiological functions at complete rest. Activity multipliers (1.2-1.9) estimate total daily energy expenditure. Individual metabolic rates vary based on genetics, muscle mass, hormones, and other factors. Consult with a healthcare professional for personalized metabolic analysis.
