An Estimation of Your Body Fat Percentage
Body fat percentage is an important measure of overall health and fitness. It is calculated using a formula that takes into account a person’s height, weight, age, and gender. The most commonly used formula was first introduced in a research article titled “Body mass index as a measure of body fatness: age- and sex-specific prediction formula,” published in the British Journal of Nutrition in 1991, with P. Deurenberg as the lead researcher.
The formula uses a person’s body mass index (BMI) to estimate their body fat percentage. For men, the formula is (1.20 x BMI) + (0.23 x Age) – 16.2, while for women, it is (1.20 x BMI) + (0.23 x Age) – 5.4. BMI is calculated by dividing a person’s weight in kilograms by their height in meters squared.
Using this formula, we have created a body fat percentage calculator. It includes input fields for a person’s height and weight in centimetres and kilograms, respectively. The calculator also provides a result that falls within a certain range, which can be used to determine if the person’s body fat percentage is within a healthy range for their age and gender.
For men, the healthy range of body fat percentage is as follows:
Essential fat: 2-5%
Obese: 25% or higher
For women, the healthy range of body fat percentage is as follows:
Essential fat: 10-13%
Obese: 32% or higher
Essential fat is the minimum amount of body fat that is necessary for a person to maintain basic physical and physiological health. For men, this is generally around 2-5% body fat, while for women it is around 10-13%.
It is important to note that body fat percentage is just one of many measures of overall health and fitness. Other factors such as diet, exercise, and genetics can also play a significant role. Additionally, while this formula is widely used, it is not perfect and may not provide accurate results for everyone.
