1. What is BMR?

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

2. How Does the Calculator Work?

The calculator uses the 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 at complete rest.

3. Importance of BMR Calculation

Details: Knowing your BMR is essential for creating effective weight management plans, whether for weight loss, maintenance, or gain. It serves as the foundation for calculating your total daily energy expenditure (TDEE).

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). For accurate results, use your current measurements.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this BMR calculation?
A: This formula provides a reasonable estimate for most people, but individual variations in metabolism mean it may not be 100% accurate for everyone.

Q2: Should I use my current weight or goal weight?
A: Always use your current weight for the most accurate BMR calculation, as your metabolism is based on your current body composition.

Q3: How often does BMR change?
A: BMR changes with age, weight fluctuations, muscle mass changes, and hormonal factors. It's recommended to recalculate every few months or after significant weight changes.

Q4: Can I increase my BMR?
A: Yes, building muscle through strength training, staying hydrated, getting enough sleep, and eating adequate protein can help increase your BMR over time.

Q5: How is BMR different from TDEE?
A: BMR represents calories burned at complete rest, while TDEE (Total Daily Energy Expenditure) includes all activities and represents your total daily calorie burn.
