RFM-FatPercentCalculator

RFM-FatPercentCalculator (RFM -- Relative Fat Mass) predicts body fat mass using only two body measurements - height and waist circumference. This estimation is more accurate than the well-known body mass index (BMI), which often misclassifies obesity.

Body fat (in other words adipose tissue) is an essential component of the human body. Its primary function is energy storage, but it also has other vital functions, such as protecting internal organs and producing hormones (e.g., leptin). The percentage of body fat in people generally varies according to age and sex. Women usually have a greater body fat percentage than men (due to reproductive and hormonal functions), and older people tend to have a higher body fat percentage.
