1. What is the NHS TDEE Equation for Weight Loss?

The NHS (National Health Service) TDEE equation calculates Total Daily Energy Expenditure with a 500 kcal deficit for sustainable weight loss. It's based on the Mifflin-St Jeor equation adapted for weight management.

2. How Does the Calculator Work?

The calculator uses the NHS TDEE equation for weight loss:

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

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 sustainable weight loss

Explanation: The equation first calculates Basal Metabolic Rate (BMR), then applies an activity multiplier, and finally subtracts 500 calories to create a deficit for weight loss.

3. Importance of TDEE Calculation for Weight Loss

Details: Accurate TDEE calculation is crucial for creating effective weight loss plans. A 500 kcal daily deficit typically results in about 0.5 kg (1 lb) of weight loss per week, which is considered safe and sustainable by the NHS.

4. Using the Calculator

Tips: Enter your current weight in kg, height in cm, age in years, and select your activity level based on your weekly exercise routine. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why subtract 500 calories for weight loss?
A: A 500 kcal daily deficit creates about 3500 kcal weekly deficit, which typically results in 0.5 kg (1 lb) of fat loss per week, considered safe and sustainable.

Q2: How accurate is this calculation?
A: The equation provides a good estimate for most people, but individual metabolism can vary. Monitor your progress and adjust as needed.

Q3: Should I eat exactly this amount every day?
A: This is a starting point. Listen to your body and adjust based on your energy levels, hunger, and weight loss progress.

Q4: What if I'm not losing weight at this calorie level?
A: You may need to adjust your calorie intake or increase physical activity. Consult with a healthcare professional for personalized advice.

Q5: Is this suitable for everyone?
A: While generally safe for most adults, individuals with medical conditions should consult a doctor before starting any weight loss program.
