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 a crucial metric 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 essential for effective weight management. To lose weight, consume fewer calories than your TDEE; to gain weight, consume more. It helps create personalized diet plans and achieve fitness goals.

4. Using the Calculator

Tips: Enter your BMR value in kcal/day and select your appropriate activity level from the dropdown menu. Ensure your BMR is calculated accurately for best results.

5. Frequently Asked Questions (FAQ)

Q1: How do I calculate my BMR?
A: BMR can be calculated using formulas like Mifflin-St Jeor or Harris-Benedict equations, which consider age, gender, height, and weight.

Q2: How accurate is TDEE calculation?
A: While formulas provide good estimates, individual variations exist. For precise measurements, professional metabolic testing is recommended.

Q3: Should I adjust my TDEE over time?
A: Yes, as you lose/gain weight or change activity levels, your TDEE will change and should be recalculated periodically.

Q4: Can TDEE help with muscle building?
A: Absolutely. To build muscle, you typically need to consume slightly more calories than your TDEE while following a proper strength training program.

Q5: How often should I recalculate my TDEE?
A: Recalculate every 4-6 weeks, or whenever your weight changes significantly or your activity level alters substantially.
