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. The result is your basal metabolic rate BMR. Males: Ageīoth the Katch-McArdle and the Cunningham formulas use lean body mass to estimate your resting metabolic rate. Use the Harris-Benedict equation for women: BMR 655.1 + (9.563 × weight in kg) + (1.850 × height in cm) - (4.676 × age).

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. While losing weight or building lean body mass, you must calculate exactly how many calories you should consume. This skewed the results for other communities. BMR Calculator Methodology For Weight Loss. The Basal Metabolic Rate calculator is a simple tool used to estimate the basal metabolic rate of your body and measure the kilocalories required to sustain. This ideal weight calculator is an approximation and based on the standard equations provided by Welltech Solutions. However, a disproportionate number of subjects in the data set were Italian men with on average higher BMR values. Your ideal body weight varies based on gender, age, and current health. The Schofield equation was published in 1985 and used by FAO/WHO/UNU (World Health Organization and others).
