1. What is BMR?

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

2. How Does the Calculator Work?

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

Where:

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

Explanation: The equation accounts for the energy needed to maintain body mass, with adjustments for height, age, and gender-specific metabolic differences.

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 total daily energy expenditure (TDEE) when multiplied by activity factors.

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, and age in years. For accurate results, measure your weight and height in the morning before eating or drinking.

5. Frequently Asked Questions (FAQ)

Q1: Why is the equation different for females?
A: Women typically have lower BMR than men due to differences in body composition (higher fat percentage and lower muscle mass).

Q2: What are normal BMR values for women?
A: Average BMR for women ranges between 1200-1500 kcal/day, but varies based on body size and composition.

Q3: When should I measure my BMR?
A: For most accurate results, measure in the morning after waking up, before eating, and after a full night's sleep.

Q4: Does muscle mass affect BMR?
A: Yes, muscle tissue burns more calories at rest than fat tissue. This equation provides an estimate that doesn't account for individual variations in body composition.

Q5: How can I use my BMR for weight management?
A: Multiply your BMR by an activity factor to estimate daily calorie needs. Consuming fewer calories than this amount leads to weight loss, while consuming more leads to weight gain.
