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:

Where:

• \( weight \) — Body weight in kilograms
• \( height \) — Height in centimeters
• \( age \) — Age in years
• \( s \) — +5 for males, -161 for females

Explanation: This equation accounts for the fact that men typically have more muscle mass than women, which affects their basal metabolic rate.

3. Importance of BMR Calculation

Details: Knowing your BMR helps in creating effective weight management plans, whether for weight loss, gain, or maintenance. 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, age in years, and select your gender. For most accurate results, measure your weight and height right before using the calculator.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this BMR calculation?
A: The Mifflin-St Jeor Equation is considered the most accurate for estimating BMR in healthy individuals, with about 90% accuracy.

Q2: Why is BMR different for men and women?
A: Men generally have more muscle mass and less body fat than women of the same weight, resulting in a higher BMR.

Q3: Does BMR change with age?
A: Yes, BMR typically decreases with age due to loss of muscle mass and changes in hormonal and neurological processes.

Q4: How can I increase my BMR?
A: Increasing muscle mass through strength training can raise your BMR, as muscle tissue burns more calories at rest than fat tissue.

Q5: Should I eat below my BMR to lose weight?
A: It's generally not recommended to eat below your BMR as this can slow your metabolism. Instead, create a deficit based on your TDEE.
