1. What is BMR?

Basal Metabolic Rate (BMR) is the number of calories your body needs to maintain basic physiological functions at rest. It accounts for 60-75% of daily calorie expenditure in most people.

2. How Does the Calculator Work?

The calculator uses the Mifflin-St Jeor Equation:

Where:

• \( weight \) — Body weight in kilograms
• \( height \) — Height in centimeters
• \( age \) — Age in years
• \( gender\_factor \) — +5 for men, -161 for women

Explanation: This equation provides the most accurate estimate of BMR for the general population.

3. Importance of BMR Calculation

Details: Knowing your BMR is essential for weight management, as it helps determine your daily calorie needs. It's particularly relevant for UK weight loss injection programs to personalize treatment plans.

4. Using the Calculator

Tips: Enter weight in kg, height in cm, age in years, and select gender. For accurate results, measure weight and height without clothes and shoes.

5. Frequently Asked Questions (FAQ)

Q1: Why is BMR important for weight loss injections?
A: BMR helps clinicians determine appropriate dosage and expected metabolic response to weight loss injections.

Q2: What are typical BMR values?
A: Average BMR ranges from 1200-2000 kcal/day for adults, varying by size, gender, and age.

Q3: How often should I recalculate my BMR?
A: Recalculate after significant weight changes (5+ kg) or every 6 months during weight loss programs.

Q4: Does this account for activity level?
A: No, this is basal rate only. Multiply by activity factor (1.2-1.9) for total daily energy expenditure.

Q5: How accurate is this calculator?
A: It provides a good estimate for most people, but individual variations can be ±10% due to body composition differences.
