Note that in the BMR/RMR calculator above the lean body mass is automatically calculated using the Boer formula if body fat percentage is not provided. If you know your body fat percentage, lean body mass can be calculated by the following formula: (1 - Body Fat Percentage / 100) x Weight. Males: Ageīoth the Katch-McArdle and the Cunningham formulas use lean body mass to estimate your resting metabolic rate. Your BMI (Body Mass Index) is a calculation that is used to determine if a person is overweight that applies to both adult men and women. A BMI of 30 kg/m² or higher is considered obese. A BMI between 25 kg/m² and 29.9 kg/m² is considered overweight. A BMI of less than 18.5 kg/m² is considered underweight. Specifically designed to consider the unique physiological and biological factors that affect women, this calculator provides an accurate assessment of body weight and potential health risks. Males: AgeĪs the Schofield equation above was proven not to be very reliable for many, a new series of equations was developed in 2005 which consisted of a database of 10,552 BMR values that had a more diverse set of subjects. A BMI between 18.5 and 25 kg/m² indicates a normal weight. The BMI calculator for women is a valuable tool in assessing and managing weight. This skewed the results for other communities.
However, a disproportionate number of subjects in the data set were Italian men with on average higher BMR values. Healthcare providers calculate BMI by using weight in kilograms (kg) divided by the square of height in meters (m2). The Schofield equation was published in 1985 and used by FAO/WHO/UNU (World Health Organization and others). Body mass index (BMI) is a medical screening tool that measures the ratio of your height to your weight to estimate the amount of body fat you have. Body mass index, or BMI, gives an indication of your body size.
