TDEE Formula:
| From: | To: |
Total Daily Energy Expenditure (TDEE) represents the total number of calories your body burns in a day, including basal metabolic rate (BMR) and calories burned through physical activity. It's a crucial metric for weight management and nutritional planning.
The calculator uses the TDEE formula:
Where:
Explanation: The equation calculates total energy expenditure by multiplying your basal metabolic rate (the calories your body burns at rest) by an activity factor that accounts for your daily physical activity level.
Details: Knowing your TDEE is essential for effective weight management. It helps determine appropriate calorie intake for weight loss, maintenance, or gain, and provides a scientific basis for creating personalized nutrition plans.
Tips: Enter your basal metabolic rate (BMR) in kcal/day and select your appropriate activity factor based on your weekly exercise routine and daily activity level. All values must be valid (BMR > 0).
Q1: How do I calculate my BMR?
A: BMR can be calculated using formulas like Mifflin-St Jeor or Harris-Benedict equations, which consider factors like age, gender, height, and weight.
Q2: What activity factor should I choose?
A: Select the activity factor that best matches your weekly exercise routine and daily activity level. Be honest about your activity to get accurate results.
Q3: How often should I recalculate my TDEE?
A: Recalculate your TDEE whenever your weight changes significantly (±5 kg/10 lbs) or your activity level changes substantially.
Q4: Can TDEE vary day to day?
A: Yes, TDEE can vary based on daily activity levels, but the calculator provides an average estimate based on your typical activity patterns.
Q5: How accurate is the TDEE calculation?
A: While the calculation provides a good estimate, individual variations in metabolism and activity can affect accuracy. For precise measurements, professional metabolic testing may be needed.
