1. What is TDEE?

TDEE (Total Daily Energy Expenditure) represents the total number of calories your body burns in a day, including basal metabolic rate (BMR) and calories burned through physical activity.

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 Levels:

• Sedentary (1.2): Little or no exercise
• Lightly Active (1.375): Light exercise 1-3 days/week
• Moderately Active (1.55): Moderate exercise 3-5 days/week
• Very Active (1.725): Hard exercise 6-7 days/week
• Extra Active (1.9): Very hard exercise and physical job

3. Importance of TDEE Calculation

Details: Knowing your TDEE is essential for weight management. To lose weight, consume fewer calories than your TDEE; to gain weight, consume more. Accurate TDEE calculation helps create effective diet plans.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: How is BMR different from TDEE?
A: BMR represents calories burned at complete rest, while TDEE includes all daily activities and exercise.

Q2: How often should I recalculate my TDEE?
A: Recalculate when your weight changes significantly (±5kg) or when your activity level changes substantially.

Q3: Are TDEE calculations accurate for everyone?
A: While formulas provide good estimates, individual variations exist due to metabolism, body composition, and other factors.

Q4: Can I use TDEE for muscle building?
A: Yes, consuming 300-500 calories above your TDEE can support muscle growth when combined with strength training.

Q5: How does age affect TDEE?
A: TDEE typically decreases with age due to reduced muscle mass and metabolic rate. Regular exercise can help maintain higher TDEE.
