1. What is the UK NHS TDEE Calculator?

The UK NHS TDEE Calculator estimates your Total Daily Energy Expenditure using the Harris-Benedict equation adapted for the UK National Health Service guidelines. It calculates how many calories you burn each day based on your weight, height, age, and activity level.

2. How Does the Calculator Work?

The calculator uses the Harris-Benedict equation for women:

\[ TDEE = (655.1 + 9.563 \times weight + 1.850 \times height - 4.676 \times age) \times activity\ factor \]

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 Basal Metabolic Rate (BMR) first, then multiplies by an activity factor to estimate total daily energy expenditure.

3. Importance of TDEE Calculation

Details: Knowing your TDEE is essential for weight management, whether you want to lose, maintain, or gain weight. It helps create appropriate calorie targets for your goals.

4. Using the Calculator

Tips: Enter your current weight in kg, height in cm, age in years, and select your activity level. For accurate results, use recent measurements and be honest about your activity level.

5. Frequently Asked Questions (FAQ)

Q1: Why use the Harris-Benedict equation?
A: The Harris-Benedict equation is one of the most widely used and validated equations for estimating basal metabolic rate and is recommended by the UK NHS for general population use.

Q2: What are typical TDEE values?
A: TDEE varies significantly based on individual factors. Most adults have a TDEE between 1,800-3,000 kcal/day, with athletes and very active individuals potentially higher.

Q3: How often should I recalculate my TDEE?
A: Recalculate whenever your weight changes significantly (±2-3 kg) or your activity level changes substantially.

Q4: Are there limitations to this calculation?
A: This provides an estimate. Individual variations in metabolism, body composition, and other factors can affect actual energy expenditure.

Q5: Should I use this for weight loss planning?
A: Yes, but consult with a healthcare professional for personalized advice, especially if you have medical conditions or specific health goals.
