1. What is Total Daily Energy Expenditure?

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 essential for weight management and nutritional planning.

2. How Does the Calculator Work?

The calculator uses the TDEE formula:

Where:

• \( BMR \) — Basal Metabolic Rate (calories burned at rest)
• \( Activity Factor \) — Multiplier based on activity level

Activity Factors:

• Sedentary (little or no exercise): 1.2
• Lightly active (light exercise 1-3 days/week): 1.375
• Moderately active (moderate exercise 3-5 days/week): 1.55
• Very active (hard exercise 6-7 days/week): 1.725
• Extra active (very hard exercise, physical job): 1.9

3. Importance of TDEE Calculation

Details: Knowing your TDEE is crucial for weight management. To lose weight, consume fewer calories than your TDEE; to gain weight, consume more. It helps create personalized diet and exercise plans.

4. Using the Calculator

Tips: Enter your BMR in kcal/day and select your activity level based on your typical weekly exercise routine. Ensure BMR is calculated accurately for best results.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between BMR and TDEE?
A: BMR is calories burned at complete rest, while TDEE includes all daily activities and exercise.

Q2: How accurate is the TDEE calculation?
A: It provides a good estimate, but individual variations in metabolism and activity patterns can affect accuracy.

Q3: Should I use TDEE for weight loss?
A: Yes, consuming 300-500 calories less than your TDEE typically results in safe weight loss of 0.5-1 kg per week.

Q4: How often should I recalculate my TDEE?
A: Recalculate every 4-6 weeks or after significant weight changes or activity level modifications.

Q5: Can TDEE change throughout the day?
A: TDEE is a daily average, but energy expenditure varies based on activity levels throughout the day.
