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 women:

Where:

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

Explanation: This equation estimates the calories burned at complete rest based on body composition factors.

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).

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.

5. Frequently Asked Questions (FAQ)

Q1: How does BMR differ for men and women?
A: Women generally have lower BMR than men of the same weight due to typically higher body fat percentage and lower muscle mass.

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

Q3: How often should I recalculate my BMR?
A: Recalculate after significant weight changes (5+ kg) or annually as metabolism slows with age.

Q4: Does muscle mass affect BMR?
A: Yes, muscle tissue burns more calories at rest than fat tissue, so those with more muscle mass have higher BMR.

Q5: How can I increase my BMR?
A: Building muscle through strength training and maintaining an active lifestyle can help increase your BMR over time.
