1. What is TDEE?

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. It's crucial for weight management and nutrition planning.

2. How Does the Calculator Work?

The calculator uses the Mifflin-St Jeor Equation for females:

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 calculates your basal metabolic rate (BMR) and then multiplies it by an activity factor to estimate your total daily energy needs.

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. Maintaining weight requires matching calorie intake to TDEE.

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, age in years, and select your activity level based on your weekly exercise routine. Use accurate measurements for best results.

5. Frequently Asked Questions (FAQ)

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

Q2: How accurate is this calculation?
A: The Mifflin-St Jeor Equation is considered one of the most accurate BMR formulas, but individual variations may occur.

Q3: Should I use metric or imperial measurements?
A: This calculator uses metric units (kg and cm) for better accuracy with the formula.

Q4: How often should I recalculate my TDEE?
A: Recalculate every 4-6 weeks or whenever your weight, activity level, or body composition changes significantly.

Q5: Can men use this calculator?
A: This specific formula is for females. Men should use the male version: BMR = 66.5 + (13.75 × weight) + (5.003 × height) - (6.75 × age)
