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:

• \( weight_{stones} \) — Weight in stones
• \( height \) — Height in centimeters
• \( age \) — Age in years
• \( activity\_factor \) — Multiplier based on activity level

Explanation: The equation first converts weight from stones to kilograms, then calculates basal metabolic rate and multiplies by activity factor to estimate total daily energy expenditure.

3. Importance of TDEE Calculation

Details: Knowing your TDEE helps with weight management goals - consuming fewer calories than TDEE leads to weight loss, while consuming more leads to weight gain. It's fundamental for creating effective diet and exercise plans.

4. Using the Calculator

Tips: Enter weight in stones, height in centimeters, age in years, and select your appropriate activity level. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why use stones instead of kilograms or pounds?
A: This calculator is designed for users who prefer the imperial stone measurement system commonly used in the UK and Ireland.

Q2: How accurate is this TDEE calculation?
A: It provides a good estimate for most people, but individual variations in metabolism may affect accuracy. Consider it a starting point for your calorie calculations.

Q3: Should I use my current weight or goal weight?
A: Always use your current weight for accurate TDEE calculation. Adjust as your weight changes over time.

Q4: How often should I recalculate my TDEE?
A: Recalculate whenever your weight changes significantly (5+ pounds) or your activity level changes substantially.

Q5: Can TDEE change with age?
A: Yes, metabolism typically slows with age, so your TDEE may decrease over time even if weight and activity remain constant.
