1. What is BMR?

Basal Metabolic Rate (BMR) is the number of calories your body needs to maintain basic physiological functions at rest, such as breathing, circulation, and cell production. It represents the minimum energy required to keep your body functioning.

2. How Does the Calculator Work?

The calculator uses the Mifflin-St Jeor equation for women:

Where:

• \( weight \) — Body weight in kilograms (kg)
• \( height \) — Height in centimeters (cm)
• \( age \) — Age in years

Explanation: This equation accounts for the fact that women typically have lower BMR than men due to differences in body composition.

3. Importance of BMR Calculation

Details: Knowing your BMR helps in creating personalized diet plans 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. For accurate results, measure your weight and height in the morning before eating.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this BMR calculation?
A: The Mifflin-St Jeor equation is considered about 70-80% accurate for most people. For precise measurement, clinical metabolic testing is needed.

Q2: Why is BMR different for women and men?
A: Men typically have more muscle mass and less body fat than women, resulting in higher BMR due to muscle tissue being more metabolically active.

Q3: How often should I recalculate my BMR?
A: Recalculate whenever your weight changes significantly (5+ kg), or every 6 months as metabolism changes with age.

Q4: What factors can affect my BMR?
A: Muscle mass, body size, age, genetics, hormonal status, and environmental temperature can all influence BMR.

Q5: How can I increase my BMR?
A: Building muscle through strength training, staying active, eating enough protein, and getting quality sleep can help increase your BMR.
