1. What is the NHS BMR Equation?

The NHS BMR (Basal Metabolic Rate) equation estimates the number of calories your body needs to perform basic life-sustaining functions at rest. This calculation is particularly useful for weight loss planning as it helps determine your daily calorie requirements.

2. How Does the Calculator Work?

The calculator uses the NHS BMR equation:

Where:

• \( weight \) — Body weight in kilograms (kg)
• \( height \) — Height in centimeters (cm)
• \( age \) — Age in years

Explanation: This equation calculates the minimum energy expenditure required to maintain vital body functions while at complete rest.

3. Importance of BMR Calculation for Weight Loss

Details: Knowing your BMR is essential for creating an effective weight loss plan. It helps determine your Total Daily Energy Expenditure (TDEE) when combined with your activity level, allowing you to create a calorie deficit for weight loss.

4. Using the Calculator

Tips: Enter your weight in kilograms, height in centimeters, and age in years. All values must be valid (weight > 0, height > 0, age between 1-120).

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between BMR and TDEE?
A: BMR represents calories burned at complete rest, while TDEE (Total Daily Energy Expenditure) includes all daily activities and exercise.

Q2: How can I use BMR for weight loss?
A: Multiply your BMR by your activity level factor to get TDEE, then create a calorie deficit of 500-1000 calories per day for safe weight loss.

Q3: Is this equation accurate for everyone?
A: While generally accurate, individual variations in metabolism, muscle mass, and other factors can affect actual BMR.

Q4: How often should I recalculate my BMR?
A: Recalculate when you experience significant weight changes (5+ kg) or every 6 months as part of your weight management plan.

Q5: Does this equation work for both men and women?
A: This specific equation is designed for women. For men, a different equation would typically be used.
