1. What is Basal Metabolic Rate (BMR)?

Basal Metabolic Rate (BMR) is the number of calories your body needs to perform basic life-sustaining functions at rest. This includes breathing, circulation, cell production, and nutrient processing.

2. How Does the Calculator Work?

The calculator uses the BMR formula for women:

Where:

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

Explanation: This equation estimates the minimum energy required to maintain vital functions while at complete rest.

3. Importance of BMR Calculation

Details: Knowing your BMR is essential for creating effective weight management plans, whether for weight loss, maintenance, or gain. It forms the foundation for calculating your total daily energy expenditure.

4. Using the Calculator

Tips: Enter your weight in kilograms, height in centimeters, and age in years. All values must be valid positive numbers. For accurate results, use your most recent measurements.

5. Frequently Asked Questions (FAQ)

Q1: Why is the BMR formula different for women?
A: Women typically have a lower BMR than men due to differences in body composition, with women generally having more body fat and less muscle mass.

Q2: How accurate is this BMR calculation?
A: This formula provides a good estimate for most women, but individual variations in metabolism, body composition, and other factors can affect actual BMR.

Q3: When should I measure my BMR?
A: For the most accurate measurement, BMR should be measured after 8 hours of sleep and 12 hours of fasting in a temperature-controlled environment.

Q4: What factors can affect BMR?
A: BMR is influenced by age, gender, weight, height, body composition, genetics, hormonal factors, and environmental temperature.

Q5: How can I use my BMR for weight management?
A: Multiply your BMR by an activity factor to determine your total daily energy needs, then adjust your calorie intake based on your weight goals.
