1. What is Basal Metabolic Rate (BMR)?

Basal Metabolic Rate (BMR) is the number of calories your body needs to perform basic life-sustaining functions while at complete rest. This includes breathing, circulation, cell production, and nutrient processing.

2. How Does the BMR Calculator Work?

The calculator uses the Mifflin-St Jeor Equation:

Where:

• Weight — in kilograms (kg)
• Height — in centimeters (cm)
• Age — in years

Explanation: This equation is considered one of the most accurate for calculating BMR and is widely used in clinical settings.

3. Importance of BMR for Weight Loss

Details: Knowing your BMR is essential for effective weight management. It helps determine your daily calorie needs, allowing you to create a calorie deficit for weight loss or a surplus for weight gain.

4. Using the Calculator

Tips: Enter your weight in kilograms, height in centimeters, age in years, and select your gender. For accurate results, use your current measurements.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is the BMR calculation?
A: The Mifflin-St Jeor Equation is about 90% accurate for most people, though individual variations in metabolism can affect results.

Q2: How often should I recalculate my BMR?
A: Recalculate whenever your weight changes significantly (5+ kg) or annually as you age, since BMR decreases with age.

Q3: What's the difference between BMR and TDEE?
A: BMR is calories burned at rest, while TDEE (Total Daily Energy Expenditure) includes all activities. TDEE = BMR × activity level.

Q4: Can I increase my BMR?
A: Yes, through building muscle mass, regular exercise, proper hydration, and adequate protein intake.

Q5: How should I use my BMR for weight loss?
A: Create a calorie deficit of 500-1000 calories per day below your TDEE for safe weight loss of 0.5-1kg per week.
