TDEE Equation:
| From: | To: |
The TDEE (Total Daily Energy Expenditure) calculator estimates your total daily calorie needs based on your Basal Metabolic Rate (BMR) and activity level. It represents the total number of calories you burn in a day, including all activities and bodily functions.
The calculator uses the TDEE equation:
Where:
Explanation: The equation calculates your total daily energy expenditure by multiplying your basal metabolic rate by an activity factor that represents your daily physical activity level.
Details: Knowing your TDEE is crucial for weight management, whether your goal is weight loss, weight maintenance, or muscle gain. It helps determine appropriate calorie intake for your specific goals and activity level.
Tips: Enter your BMR in kcal/day and select your activity level from the dropdown menu. Choose the activity factor that best matches your weekly exercise routine and daily activity level for accurate results.
Q1: What is the difference between BMR and TDEE?
A: BMR represents calories burned at complete rest, while TDEE includes all daily activities and represents total calories burned in a day.
Q2: How accurate is the TDEE calculation?
A: The calculation provides a good estimate, but individual variations in metabolism and activity patterns can affect accuracy. It's best used as a starting point.
Q3: Should I use sedentary or active factor if I have a desk job but exercise regularly?
A: Choose the activity factor based on your exercise frequency and intensity, not your occupation. Regular exercisers should use the appropriate activity level.
Q4: How often should I recalculate my TDEE?
A: Recalculate when your weight changes significantly, your activity level changes, or every 4-6 weeks to account for metabolic adaptations.
Q5: Can TDEE be used for weight loss planning?
A: Yes, creating a calorie deficit of 500-1000 calories below your TDEE typically results in safe and sustainable weight loss of 1-2 pounds per week.
