1. What is the Mifflin-St Jeor Equation?

The Mifflin-St Jeor equation is a widely used formula for estimating basal metabolic rate (BMR), which represents the number of calories your body needs at rest to maintain basic physiological functions. It's considered one of the most accurate BMR equations for the general population.

2. How Does the Calculator Work?

The calculator uses the Mifflin-St Jeor equation for women:

\[ BMR = 10 \times weight + 6.25 \times height - 5 \times age - 161 \]

Where:

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

Explanation: The equation calculates the minimum energy expenditure required to sustain vital 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 goals for health maintenance or weight loss.

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, use current measurements.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between BMR and RMR?
A: BMR (Basal Metabolic Rate) measures energy expenditure at complete rest, while RMR (Resting Metabolic Rate) measures energy expenditure at rest but may include minimal activity. BMR is typically slightly lower than RMR.

Q2: How often should I recalculate my BMR?
A: You should recalculate your BMR whenever your weight changes significantly (5+ kg), or every 6-12 months as part of regular health assessment.

Q3: Why is the equation different for women?
A: Women typically have lower BMR than men due to differences in body composition, with women generally having higher body fat percentage and lower muscle mass.

Q4: Are there limitations to this equation?
A: The equation may be less accurate for extremely muscular individuals, those with very high or very low body fat percentages, pregnant women, and elderly individuals.

Q5: How do I use BMR for weight management?
A: Multiply your BMR by an activity factor to estimate total daily energy expenditure, then adjust calorie intake based on your weight goals (deficit for weight loss, surplus for weight gain).
