1. What is the NHS TDEE Calculator for Women?

The NHS TDEE (Total Daily Energy Expenditure) Calculator for Women estimates the total number of calories you burn daily, adjusted for weight loss by creating a 500-calorie deficit. This approach follows NHS guidelines for sustainable weight management.

2. How Does the Calculator Work?

The calculator uses the NHS-recommended 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 weight loss

Explanation: The equation calculates Basal Metabolic Rate (BMR) using Mifflin-St Jeor formula, then adjusts for activity level, and finally subtracts 500 calories to create a weight loss deficit.

3. Importance of TDEE Calculation for Weight Loss

Details: Accurate TDEE calculation is crucial for effective weight management. A 500-calorie daily deficit typically results in about 0.5kg (1lb) 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 typical 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-calorie daily deficit creates approximately 3500 calories deficit per week, which typically results in about 0.5kg (1lb) of weight loss, following NHS guidelines for safe weight reduction.

Q2: What activity factor should I choose?
A: Select the activity level that best matches your typical weekly exercise routine. Be honest about your activity to get the most accurate TDEE calculation.

Q3: Is this calculator only for women?
A: Yes, this specific calculator uses the Mifflin-St Jeor formula optimized for women. Men should use a different equation with different coefficients.

Q4: How often should I recalculate my TDEE?
A: Recalculate every 4-6 weeks or after significant weight changes (5kg or more) to ensure your calorie targets remain appropriate for continued progress.

Q5: Are there any medical conditions that affect TDEE?
A: Yes, certain medical conditions, medications, and metabolic disorders can affect your metabolic rate. Consult with a healthcare professional for personalized advice.
