1. What is the BMR Calculator?

The BMR (Basal Metabolic Rate) calculator estimates the number of calories your body needs to maintain basic physiological functions at rest. It provides an essential baseline for determining daily calorie needs.

2. How Does the Calculator Work?

The calculator uses the BMR equation:

Where:

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

Explanation: This equation calculates the basal metabolic rate based on your body's basic energy requirements at complete rest.

3. Importance of BMR Calculation

Details: Knowing your BMR is crucial for weight management, creating effective diet plans, and understanding your body's energy needs for maintaining basic bodily functions.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What is Basal Metabolic Rate (BMR)?
A: BMR is the number of calories your body needs to perform basic life-sustaining functions like breathing, circulation, and cell production while at complete rest.

Q2: How accurate is this BMR calculation?
A: While this equation provides a good estimate, individual BMR can vary based on factors like muscle mass, body composition, and genetic factors.

Q3: Should I use BMR for weight loss planning?
A: Yes, BMR serves as the foundation for calculating your total daily energy expenditure (TDEE), which helps determine appropriate calorie intake for weight loss or gain.

Q4: How often should I recalculate my BMR?
A: Recalculate your BMR whenever your weight changes significantly (5+ kg) or as you age, since these factors affect your metabolic rate.

Q5: Are there other factors that affect BMR?
A: Yes, factors like thyroid function, body temperature, stress levels, and pregnancy can also influence your basal metabolic rate.
