Understanding BMR and TDEE
BMR (Basal Metabolic Rate) represents the calories your body burns at rest to maintain vital functions. TDEE (Total Daily Energy Expenditure) takes into account your physical activity level.
Basal Metabolic Rate (BMR)
This is the minimum energy your body needs to function: breathing, blood circulation, temperature regulation, etc.
Total Daily Energy Expenditure (TDEE)
TDEE = BMR × activity coefficient. This is the actual number of calories you burn each day, accounting for your physical activity.
Frequently Asked Questions
BMR is the number of calories your body burns at rest to maintain vital functions (breathing, circulation, body temperature). It accounts for 60-70% of your daily energy expenditure.
TDEE (Total Daily Energy Expenditure) is the total number of calories you burn each day including physical activity. It's calculated by multiplying your BMR by an activity coefficient.
For healthy weight loss, create a caloric deficit of 300-500 kcal per day, which results in approximately 1 lb of weight loss per week. Never go below your BMR to avoid slowing down your metabolism.
There are several calculation formulas (Mifflin-St Jeor, Harris-Benedict, Katch-McArdle) that give slightly different results. Our calculator uses the Mifflin-St Jeor formula, considered the most accurate for the general population.
