Biological Constants
Women generally have a higher percentage of essential body fat, which is metabolically distinct. Our MSJ implementation uses a -161 constant to professionally adjust for these physiological realities.
The Female Offset
-161 kcal
Standardized reduction for gender-specific mass distribution.
Hormonal Variation & REE
Basal Metabolic Rate in women is not a static number. Research suggests that during the **Luteal Phase** of the menstrual cycle, BMR can increase by **2% to 11%** due to the thermogenic effect of progesterone. This calculator provides the essential baseline from which these fluctuations occur.
Follicular Phase
Lower metabolic baseline; standardized BMR applies.
Luteal Phase
Potentially higher calorie burn; monitor energy levels.
Accuracy Benchmarks
We utilize the **Mifflin-St Jeor formula** because it has been proven to be the most reliable estimator of resting energy expenditure in the modern female population, particularly for those with a healthy BMI range.
