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 BMR equation for females:

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 size and age.

3. Importance of BMR Calculation

Details: Knowing your BMR helps determine your daily caloric needs for weight maintenance, loss, or gain. It's 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 weight in the morning before eating and after using the bathroom.

5. Frequently Asked Questions (FAQ)

Q1: How does BMR differ between males and females?
A: Females generally have lower BMR than males of similar size due to differences in body composition (higher fat percentage).

Q2: What factors affect BMR?
A: Muscle mass, body size, age, genetics, hormone levels, and environmental temperature can all influence BMR.

Q3: How often should I recalculate my BMR?
A: Recalculate when you experience significant weight changes (±5kg) or every year as you age.

Q4: Does pregnancy affect BMR?
A: Yes, BMR increases during pregnancy due to the metabolic demands of the growing fetus.

Q5: How can I increase my BMR?
A: Building muscle through strength training can increase BMR as muscle tissue burns more calories at rest than fat tissue.
