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 your 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 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: Why is the equation different for women?
A: Women typically have higher body fat percentages and different hormonal profiles, which affect metabolic rate.

Q2: What are typical BMR values for women?
A: Average BMR for women ranges from 1200-1600 kcal/day, but varies based on size, age, and body composition.

Q3: When should I measure for most accurate 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, so those with more muscle mass typically have higher BMR.

Q5: How often should I recalculate my BMR?
A: Recalculate whenever your weight changes significantly (5+ kg) or annually as you age.
