1. What is TDEE?

TDEE (Total Daily Energy Expenditure) represents the total number of calories you burn in a day, including basal metabolic rate and physical activity. It's crucial for weight management.

2. How Does the Calculator Work?

The calculator uses the Mifflin-St Jeor equation for women:

Where:

• \( weight \) — Body weight in kilograms
• \( height \) — Height in centimeters
• \( age \) — Age in years
• \( activity\ factor \) — Multiplier based on activity level
• \( deficit \) — Desired calorie deficit for weight loss

Explanation: The equation calculates your basal metabolic rate then adjusts for activity level to determine total daily energy expenditure.

3. Importance of TDEE Calculation

Details: Knowing your TDEE helps create an effective weight loss plan. A deficit of 500 kcal/day typically results in about 0.5kg weight loss per week.

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, age in years, select your activity level, and desired calorie deficit. For sustainable weight loss, a 300-500 kcal deficit is recommended.

5. Frequently Asked Questions (FAQ)

Q1: Why use the Mifflin-St Jeor equation?
A: It's currently considered the most accurate equation for estimating calorie needs in healthy individuals.

Q2: What are typical activity factors?
A: Sedentary (1.2), Lightly active (1.375), Moderately active (1.55), Very active (1.725), Extra active (1.9).

Q3: How accurate is this calculator?
A: It provides a good estimate, but individual variations exist. Adjust based on your actual results over time.

Q4: What's a safe calorie deficit?
A: Generally 300-500 kcal/day for gradual weight loss. Avoid going below 1200 kcal/day without medical supervision.

Q5: Should I adjust my intake as I lose weight?
A: Yes, recalculate your TDEE periodically as your weight changes to maintain an appropriate deficit.
