1. What is BMR?

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

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 basal metabolic rate based on your body composition and age, providing an estimate of your daily calorie needs at complete rest.

3. Importance of BMR Calculation

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

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, 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: What factors affect BMR?
A: BMR is influenced by age, gender, body composition, genetics, and hormonal factors. Muscle mass increases BMR while fat decreases it.

Q2: How often should I recalculate my BMR?
A: You should recalculate your BMR every 3-6 months or whenever there are significant changes in your weight or body composition.

Q3: Is this equation accurate for everyone?
A: While this provides a good estimate, individual variations exist. For more precise results, consider professional metabolic testing.

Q4: How does BMR relate to weight loss?
A: To lose weight, you need to consume fewer calories than your total daily energy expenditure, which is based on your BMR plus activity level.

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