1. What is the NHS TDEE Equation?

The NHS TDEE (Total Daily Energy Expenditure) equation estimates your daily calorie needs for weight loss based on weight, height, age, and activity level. It provides a safe and sustainable approach to weight management as recommended by the UK National Health Service.

2. How Does the Calculator Work?

The calculator uses the NHS TDEE equation:

\[ TDEE = (655.1 + 9.563 \times weight + 1.850 \times height - 4.676 \times age) \times activity\ factor - 500 \]

Where:

\( weight \) — Body weight in kilograms (kg)
\( height \) — Height in centimeters (cm)
\( age \) — Age in years
\( activity\ factor \) — Multiplier based on physical activity level
\( 500 \) — Calorie deficit for safe weight loss

Explanation: The equation calculates your Basal Metabolic Rate (BMR), adjusts for activity level, then subtracts 500 calories to create a sustainable weight loss deficit.

3. Importance of TDEE Calculation

Details: Accurate TDEE calculation is crucial for effective weight management, ensuring you create an appropriate calorie deficit without compromising nutrition or health.

4. Using the Calculator

Tips: Enter your current weight in kg, height in cm, age in years, and select your activity level. Use accurate measurements for best results.

5. Frequently Asked Questions (FAQ)

Q1: Why subtract 500 calories?
A: A 500-calorie daily deficit creates approximately 0.5kg (1lb) of weight loss per week, which is considered safe and sustainable by health professionals.

Q2: What if I want to lose weight faster?
A: NHS recommends not going below 1200 calories for women or 1500 for men without medical supervision. Faster weight loss can be unhealthy.

Q3: How often should I recalculate my TDEE?
A: Recalculate every 4-6 weeks or after significant weight changes (5kg or more) to ensure accuracy.

Q4: Are there limitations to this equation?
A: This provides an estimate. Individual metabolism, medical conditions, and other factors may affect actual calorie needs.

Q5: Should I combine this with exercise?
A: Yes, combining appropriate calorie intake with regular physical activity provides the best results for weight loss and overall health.
