1. What is Basal Metabolic Rate (BMR)?

Basal Metabolic Rate (BMR) represents the number of calories your body needs to perform basic life-sustaining functions at rest. It accounts for approximately 60-75% of your total daily energy expenditure.

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 calculates the minimum energy required to maintain vital body functions while at complete rest.

3. Importance of BMR Calculation

Details: Knowing your BMR is essential for creating effective weight management plans, determining daily caloric needs, and establishing appropriate nutrition strategies for health and fitness goals.

4. Using the Calculator

Tips: Enter your weight in kilograms, height in centimeters, and age in years. All values must be valid (weight > 0, height > 0, age between 1-120). For accurate results, measure your weight and height precisely.

5. Frequently Asked Questions (FAQ)

Q1: Why is the BMR equation different for females?
A: Females typically have lower BMR than males due to differences in body composition, with males generally having more muscle mass which requires more energy to maintain.

Q2: What factors can affect BMR?
A: BMR is influenced by body composition, age, genetics, hormonal factors, environmental temperature, and overall health status.

Q3: How often should I recalculate my BMR?
A: You should recalculate your BMR whenever there are significant changes in your weight, body composition, or age (typically every few months or after major lifestyle changes).

Q4: Is BMR the same as daily calorie needs?
A: No, BMR represents only the calories needed for basic bodily functions. Total daily energy expenditure includes additional calories for physical activity and food digestion.

Q5: Can I increase my BMR?
A: Yes, building muscle mass through strength training, maintaining proper hydration, and ensuring adequate protein intake can help increase your metabolic rate over time.
