TDEE Calculator - Calculate Daily Calorie Expenditure & BMR
How TDEE Is Calculated
We use the scientifically validated Mifflin-St Jeor Equation to estimate your Basal Metabolic Rate (BMR), multiplied by your activity level factor:
Mifflin-St Jeor Equation:
Male: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age) + 5
Female: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age) - 161
TDEE = BMR × Activity Multiplier
Frequently Asked Questions (FAQ)
1. What is TDEE?
TDEE stands for Total Daily Energy Expenditure. It is the total number of calories your body burns in a 24-hour period, including sleeping, working, exercising, and digesting food.
2. What is the difference between BMR and TDEE?
BMR (Basal Metabolic Rate) is the minimum energy your body requires to stay alive at complete rest. TDEE includes your BMR plus the energy expended through physical movement and physical activity.
3. How many calories should I eat to lose weight?
To lose body fat safely (about 1 lb per week), subtract 500 calories from your TDEE per day to create a moderate calorie deficit.
4. How often should I recalculate my TDEE?
You should recalculate your TDEE every time you lose or gain 5-10 lbs (2-5 kg), or if your daily activity levels change significantly.
