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 and physical activity. It's essential for nutrition planning and weight management.

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 (1.2-1.9)

Explanation: The equation calculates your total daily calorie needs by multiplying your BMR with an activity factor that represents your daily physical activity level.

3. Importance of TDEE Calculation

Details: Knowing your TDEE is crucial for weight management - to lose weight you need to consume fewer calories than your TDEE, to gain weight you need to consume more, and to maintain weight you should match your TDEE.

4. Using the Calculator

Tips: Enter your BMR in kcal/day and select your appropriate activity level based on your weekly exercise routine and daily activity patterns.

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: What activity factor should I choose?
A: Choose based on your typical weekly activity: Sedentary (1.2), Lightly active (1.375), Moderately active (1.55), Very active (1.725), or Extra active (1.9).

Q3: How accurate is TDEE calculation?
A: While formulas provide good estimates, individual variations exist. Consider it a starting point and adjust based on results.

Q4: Should I recalculate my TDEE regularly?
A: Yes, recalculate when your weight changes significantly, activity levels change, or every few months to ensure accuracy.

Q5: Can TDEE help with muscle building?
A: Yes, to build muscle you typically need to consume 250-500 calories above your TDEE while following a proper strength training program.
