1. What is BMR?

BMR (Basal Metabolic Rate) represents the number of calories your body needs to perform basic life-sustaining functions at rest. It accounts for 60-75% of your total daily energy expenditure.

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 estimates the minimum energy required to maintain vital body functions while 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 needs.

4. Using the Calculator

Tips: Enter your weight in kilograms, height in centimeters, and age in years. All values must be valid positive numbers for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What factors affect BMR?
A: BMR is influenced by age, gender, weight, height, body composition, genetics, and hormonal factors.

Q2: How often should I recalculate my BMR?
A: You should recalculate your BMR whenever your weight changes significantly (more than 5kg) or annually as you age.

Q3: Is this equation accurate for everyone?
A: While this equation provides a good estimate for most people, individual variations in metabolism may cause slight differences in actual BMR.

Q4: How does BMR differ from TDEE?
A: BMR represents calories burned at complete rest, while TDEE (Total Daily Energy Expenditure) includes all daily activities and exercise.

Q5: Can I increase my BMR?
A: Yes, through building muscle mass, regular exercise, proper nutrition, and adequate sleep can help increase your metabolic rate.
