Fitness Calculators: Calculate Fat Free Max Index

FFMI calculator estimates fat free body max index by including body fat percentage.

Traditional BMI Calculation

Obesity and obesity-related diseases are among the most prominent health problems in the world (Higher in Western Countries). In the USA and Europe, more than 40% of the population is overweight. Obesity is normally defined by the body mass index measured by body weight in kilograms divided by height in meters squared (BMI; kg/m2). BMI values between 18.5 and 24.9 kg/m2 are considered normal; individuals with BMI values from 25 to 29.9 kg/m2 are considered overweight, while those with values over 30 kg/m2 are considered obese. As a metrics tool this method of body mass index calculation continues to serve mostly sedentary populations. Because greater than 60% of our population is sedentary, and greater than 40% is overweight, this scale provides necessary metrics to both treatment (medical) and preventative (fitness) communities.

Calculation of Fat Free Body Mass Index

Unlike the BMI calculator that estimates body mass index by height and weight measurements, the Fat Free Mass Index (FFMI) calculator estimates fat free body mass index by including body fat percentage to deduce lean body mass over gross body mass. Athletes, bodybuilders, fitness and sport enthusiasts require better metrics tools to estimate fat free mass index because these populations of people typically hold lower body fat and higher muscle mass percentages.
