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 and physical activity. It's essential for weight management in Australia's health context.

2. How Does the Calculator Work?

The calculator uses the standard TDEE equation:

\[ TDEE = (10 \times weight + 6.25 \times height - 5 \times age - 161) \times activity\ factor \]

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 first, then multiplies by an activity factor to estimate total daily energy expenditure.

3. Importance of TDEE Calculation

Details: Knowing your TDEE is crucial for effective weight loss planning. Creating a calorie deficit (consuming fewer calories than your TDEE) is the fundamental principle behind weight loss in Australia's health guidelines.

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

Q2: What's a safe calorie deficit for weight loss?
A: A deficit of 500-1000 calories per day is generally safe, leading to 0.5-1kg weight loss per week according to Australian health guidelines.

Q3: Should I adjust my TDEE as I lose weight?
A: Yes, as you lose weight, your TDEE decreases. Recalculate every 4-6 weeks or after significant weight changes.

Q4: Are there different formulas for men and women?
A: This formula already accounts for gender differences through the constant (-161) which is specific to the standard equation structure.

Q5: How does activity level affect TDEE?
A: More active lifestyles significantly increase TDEE. Choose the activity factor that best matches your regular exercise routine.
