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)
• \( \text{activity factor} \) — Multiplier based on activity level (1.2-1.9)

Explanation: The equation accounts for your base metabolic rate multiplied by your daily activity level to estimate total daily calorie expenditure.

3. Importance of TDEE Calculation

Details: Knowing your TDEE is crucial for weight management, whether your goal is weight loss, maintenance, or muscle gain. It helps determine appropriate calorie intake levels.

4. Using the Calculator

Tips: Enter your BMR in kcal/day and select your appropriate activity level. All values must be valid (BMR > 0).

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 level. Be honest about your exercise habits for accurate results.

Q3: How accurate is TDEE calculation?
A: While estimates provide a good starting point, individual variations exist. Monitor your progress and adjust as needed.

Q4: Should I adjust my TDEE for weight goals?
A: Yes - subtract 500 kcal/day for weight loss (1 lb/week) or add 500 kcal/day for weight gain, then adjust based on results.

Q5: How often should I recalculate my TDEE?
A: Recalculate when your weight changes significantly (±10 lbs) or when your activity level changes substantially.
