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. For bodybuilders, understanding TDEE is crucial for optimizing nutrition plans for muscle gain or fat loss.

2. How Does the Calculator Work?

The calculator uses the Mifflin-St Jeor equation for BMR and multiplies by activity factor:

Where:

• \( weight \) — Body weight in kilograms
• \( height \) — Height in centimeters
• \( age \) — Age in years
• \( Activity\ Factor \) — Multiplier based on activity level (1.2 to 1.9)

Explanation: The equation accounts for basic metabolic needs plus additional energy expenditure from physical activity, making it ideal for bodybuilding nutrition planning.

3. Importance of TDEE Calculation for Bodybuilding

Details: Accurate TDEE calculation is essential for bodybuilders to determine appropriate calorie intake for muscle building (calorie surplus) or fat loss (calorie deficit) while maintaining optimal performance and recovery.

4. Using the Calculator

Tips: Enter accurate weight in kg, height in cm, age in years, select gender, and choose the appropriate activity factor based on your training intensity and frequency.

5. Frequently Asked Questions (FAQ)

Q1: Why is TDEE important for bodybuilding?
A: TDEE helps determine the precise calorie intake needed to support muscle growth while minimizing fat gain, or to create an optimal deficit for fat loss while preserving muscle mass.

Q2: How often should I recalculate my TDEE?
A: Recalculate every 4-6 weeks or whenever your weight changes significantly (±2-3 kg) or your activity level changes substantially.

Q3: Should I use sedentary or active activity factor?
A: Choose based on your actual activity level. Bodybuilders typically use moderately active to very active factors depending on training frequency and intensity.

Q4: How accurate is this calculation?
A: The Mifflin-St Jeor equation is about 90% accurate for most people. Individual variations in metabolism may require slight adjustments based on results.

Q5: How should I adjust calories for bulking or cutting?
A: For bulking: add 300-500 calories to TDEE. For cutting: subtract 300-500 calories from TDEE. Adjust based on weekly progress.
