BMR Calculator
Calculate your Basal Metabolic Rate and Total Daily Energy Expenditure
// BMR
Basal Metabolic Rate is the number of calories your body burns at complete rest — just to keep you alive (breathing, circulation, cell production). It accounts for 60-75% of daily energy expenditure.
// TDEE
Total Daily Energy Expenditure = BMR × activity multiplier. This is how many calories you actually burn per day including exercise. Eat below TDEE to lose weight, above to gain.
// Mifflin-St Jeor
This calculator uses the Mifflin-St Jeor equation, considered the most accurate BMR formula for most people. It replaced the older Harris-Benedict equation.
// The 500 Rule
A deficit of ~550 calories/day leads to roughly 0.5kg (1lb) of weight loss per week. Don't go below 1,200 cal/day (women) or 1,500 cal/day (men) without medical supervision.
