1. What Is The Best BMR Calculator?

The Mifflin-St Jeor equation is considered the most accurate method for calculating Basal Metabolic Rate (BMR), which represents the number of calories your body needs at complete rest to maintain basic physiological functions.

2. How Does The Calculator Work?

The calculator uses the Mifflin-St Jeor equation:

Where:

• Weight — in kilograms (kg)
• Height — in centimeters (cm)
• Age — in years
• Different constants are applied based on gender

Explanation: This equation provides the most accurate estimation of basal metabolic rate for healthy individuals and is widely used in clinical and research settings.

3. Importance of BMR Calculation

Details: Knowing your BMR is essential for creating effective weight management plans, determining daily calorie needs, and designing personalized nutrition and fitness programs.

4. Using The Calculator

Tips: Enter your weight in kilograms, height in centimeters, age in years, and select your gender. All values must be valid positive numbers for accurate results.

5. Frequently Asked Questions (FAQ)

Q1: Why is Mifflin-St Jeor considered the best BMR equation?
A: Research shows it provides the most accurate estimates of energy expenditure in both obese and non-obese individuals compared to other equations.

Q2: How often should I recalculate my BMR?
A: You should recalculate your BMR whenever your weight changes significantly (5+ kg) or annually as you age.

Q3: What factors can affect BMR?
A: Muscle mass, body composition, hormonal factors, genetics, and environmental temperature can all influence your basal metabolic rate.

Q4: How does BMR differ from TDEE?
A: BMR represents calories at complete rest, while Total Daily Energy Expenditure (TDEE) includes all daily activities and exercise.

Q5: Can I use this calculator for weight loss planning?
A: Yes, knowing your BMR is the first step in creating a calorie deficit for weight loss by determining your maintenance calories.
