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:
  • 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, 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. It helps create personalized nutrition plans and optimize fitness goals.

4. Using the Calculator

Tips: Enter your BMR in kcal/day and select your activity level based on your weekly exercise routine. Accurate BMR calculation is crucial for precise TDEE estimation.

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, which consider age, gender, weight, and height.

Q2: Why is activity factor important?
A: The activity factor accounts for calories burned through physical activity, making TDEE more accurate than BMR alone.

Q3: How often should I recalculate my TDEE?
A: Recalculate when your weight changes significantly, activity level changes, or every few months to maintain accuracy.

Q4: Can TDEE vary day to day?
A: Yes, TDEE can vary based on daily activity, exercise intensity, and other factors. The calculator provides an average estimate.

Q5: Is TDEE the same for everyone?
A: No, TDEE is personalized based on individual BMR and activity levels, making it unique to each person.
