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 crucial for weight management, whether your goal is to lose, maintain, or gain weight.
The calculator uses the TDEE formula:
Where:
Explanation: Your BMR represents the calories needed for basic bodily functions, while the activity factor accounts for additional calories burned through physical movement and exercise.
Sedentary (1.2): Little or no exercise, desk job
Lightly Active (1.375): Light exercise 1-3 days per week
Moderately Active (1.55): Moderate exercise 3-5 days per week
Very Active (1.725): Hard exercise 6-7 days per week
Extra Active (1.9): Very hard exercise and physical job
Tips: Enter your BMR value (you can calculate it using a BMR calculator first) and select your activity level based on your weekly exercise routine and daily activity patterns.
Q1: How accurate is the TDEE calculation?
A: While the formula provides a good estimate, individual variations in metabolism and activity patterns mean it should be used as a starting point rather than an exact measurement.
Q2: Should I use my current weight or goal weight for calculations?
A: Use your current weight for accurate TDEE calculation, as your energy expenditure is based on your current body composition.
Q3: How often should I recalculate my TDEE?
A: Recalculate whenever your weight changes significantly (5+ lbs) or your activity level changes substantially.
Q4: What if my activity level varies day to day?
A: Choose the activity factor that best represents your average weekly activity pattern.
Q5: Can TDEE change over time?
A: Yes, TDEE can change with age, weight fluctuations, muscle mass changes, and alterations in activity levels.
