Mifflin-St Jeor Equation for Women:
| From: | To: |
The Mifflin-St Jeor equation is a widely used formula for estimating basal metabolic rate (BMR) - the number of calories your body needs at rest to maintain basic physiological functions. It's considered one of the most accurate BMR equations available.
The calculator uses the Mifflin-St Jeor equation for women:
Where:
Explanation: The equation calculates the minimum energy requirement for basic bodily functions while at complete rest, accounting for weight, height, and age factors specific to women.
Details: Knowing your BMR is essential for creating effective weight management plans, determining daily calorie needs, and establishing appropriate nutritional goals for maintaining, losing, or gaining weight.
Tips: Enter your weight in kilograms, height in centimeters, and age in years. All values must be valid positive numbers. For best results, use accurate measurements.
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) is measured under less strict conditions. BMR is typically slightly lower than RMR.
Q2: How accurate is the Mifflin-St Jeor equation?
A: The Mifflin-St Jeor equation is considered one of the most accurate BMR prediction formulas, with an accuracy of about ±10% for most individuals.
Q3: Why is there a different equation for women?
A: Women typically have lower BMR than men due to differences in body composition, muscle mass, and hormonal factors, which the equation accounts for.
Q4: 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, since BMR decreases with age.
Q5: Can I use this BMR value for weight loss planning?
A: Yes, your BMR forms the foundation for calculating your total daily energy expenditure (TDEE), which helps determine appropriate calorie intake for weight loss or maintenance.
