Mifflin-St Jeor Equation for Women:
| From: | To: |
The Mifflin-St Jeor equation estimates basal metabolic rate (BMR) for women from weight, height, and age. It provides a more accurate assessment of resting energy expenditure than older equations, especially for modern populations.
The calculator uses the Mifflin-St Jeor equation for women:
Where:
Explanation: The equation calculates the number of calories your body needs to perform basic life-sustaining functions at complete rest.
Details: Accurate BMR estimation is crucial for determining daily caloric needs, weight management planning, and creating effective nutrition plans for health and fitness goals.
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).
Q1: Why use Mifflin-St Jeor instead of other equations?
A: The Mifflin-St Jeor equation is considered one of the most accurate BMR formulas for the general population and has been validated in numerous studies.
Q2: What are typical BMR values for women?
A: Typical BMR for adult women ranges from 1200-1600 kcal/day, though this varies based on body composition, age, and other factors.
Q3: How often should BMR be calculated?
A: BMR should be recalculated whenever there are significant changes in weight, as it directly affects your metabolic rate calculation.
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, and certain medical conditions affecting metabolism.
Q5: How does BMR relate to total daily energy expenditure?
A: BMR represents about 60-75% of total daily energy expenditure. To calculate total needs, multiply BMR by an activity factor (1.2-1.9 depending on activity level).
