BMR & TDEE Calculator
Calculate Your BMR & TDEE
Understanding BMR and TDEE
Your Basal Metabolic Rate (BMR) is the number of calories your body needs to perform basic, life-sustaining functions while at rest. These essential functions include breathing, circulation, cell production, nutrient processing, and maintaining body temperature.
Total Daily Energy Expenditure (TDEE) is the total number of calories your body burns in a 24-hour period. It includes your BMR plus the calories burned during physical activity, digestion, and other daily movements. Knowing your TDEE is crucial for effective weight management, whether you aim to lose, gain, or maintain your current weight.
Activity Levels Explained:
This calculator uses the Mifflin-St Jeor equation, a widely accepted formula for estimating BMR, and then applies an activity multiplier to determine your TDEE.
