1. What is BMR?

Basal Metabolic Rate (BMR) is the number of calories your body needs to perform basic life-sustaining functions at rest. It represents the minimum energy required to keep your body functioning, including breathing, circulation, and cell production.

2. How Does the Calculator Work?

The calculator uses the Mifflin-St Jeor equations:

Where:

• weight — Body weight in kilograms (kg)
• height — Height in centimeters (cm)
• age — Age in years
• TDEE — Total Daily Energy Expenditure

Explanation: The equation calculates your basal metabolic rate and then subtracts 500 calories to create a daily calorie deficit for gradual weight loss.

3. Importance of BMR Calculation

Details: Understanding your BMR is crucial for effective weight management. It helps determine your daily calorie needs and creates a sustainable calorie deficit for healthy weight loss without compromising essential bodily functions.

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, age in years, and select your gender. For accurate results, use current measurements and be honest about your inputs.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is the Mifflin-St Jeor equation?
A: It's considered one of the most accurate BMR equations for the general population, with about 90% accuracy for most people.

Q2: Why subtract 500 calories for weight loss?
A: A 500-calorie daily deficit creates approximately 0.5kg (1lb) of weight loss per week, which is considered safe and sustainable.

Q3: Should I eat below my BMR for faster weight loss?
A: No, eating below your BMR can slow down your metabolism and lead to muscle loss. Always aim to eat at or above your BMR.

Q4: How often should I recalculate my BMR?
A: Recalculate every 4-6 weeks or after significant weight changes (more than 5kg) to adjust your calorie intake accordingly.

Q5: Does muscle mass affect BMR?
A: Yes, muscle tissue burns more calories at rest than fat tissue. Building muscle through strength training can increase your BMR over time.
