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 weight management and nutrition planning.

2. How Does the Calculator Work?

The calculator uses the TDEE equation:

Where:

• \( weight \) — Body weight in kilograms (kg)
• \( height \) — Height in centimeters (cm)
• \( age \) — Age in years
• \( activity\ factor \) — Multiplier based on activity level (1.2-1.9)

Explanation: The equation first calculates your Basal Metabolic Rate (BMR), then multiplies it by an activity factor to estimate your total daily energy expenditure.

3. Importance of TDEE Calculation

Details: Knowing your TDEE helps you determine appropriate calorie intake for weight loss, maintenance, or muscle gain. It provides a scientific basis for creating effective diet plans.

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, age in years, and select your activity level. All values must be valid (weight > 0, height > 0, age between 1-120).

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between BMR and TDEE?
A: BMR (Basal Metabolic Rate) is the calories your body burns at complete rest, while TDEE includes all daily activities and exercise.

Q2: How accurate is this TDEE calculation?
A: This provides a good estimate, but individual variations exist due to metabolism, body composition, and other factors.

Q3: Should I use this for weight loss?
A: Yes, subtract 500 calories from your TDEE for a safe weight loss of about 0.5kg per week.

Q4: How often should I recalculate my TDEE?
A: Recalculate every 4-6 weeks or after significant weight changes to maintain accuracy.

Q5: Are there limitations to this calculation?
A: This formula works best for average individuals. Athletes, pregnant women, or those with medical conditions may need specialized calculations.
