Body mass excess

Description

The body mass excess with respect to the healthy reference population, HRP, is defined as BME ≝ m/m°. A balanced BME is BME°=1.0. Considering a height of 1.7 m, overweight (body mass index, BMI=25) is reached at a weight gain of 20 % (BME=1.2); obesity and severe obesity (BMI=30 and 35) are reached at a weight gain of 40 % and 60 % (BME=1.4 and 1.6, respectively).

Abbreviation: BME

Reference: Gnaiger 2019 MiP2019

BME - the body mass excess calculator

» BME calculator
Erich Gnaiger and Paolo Cocco: work in progress - last update 2019-11-22
The BME calculator is based on the WHO database on children up to 10 years of age (WHO Multicentre Growth Reference Study Group, WHO MGRS 2006), and on the Committee on Biological Handbooks data set (CBH; Zimmer 1962) on adoselscents to aduls, according to the tables listed below. The results have to be critically evaluated. The BME calculator applies to healthy controls (except for obesity), without sarcopenia.
  1. Open the BME calculator by clicking here (press Ctrl and left mouse click): BME calculator
  2. Click into the field Height, h [m] and enter your height in meters (not cm), using the dot (not the comma) as a separator for decimal places. Example: 1.70
  3. Click into the field Body mass, m [kg] and enter your mass (weight) in kilograms (not pounds), using the dot (not the comma) as a separator for decimal places. Example: 63.4
  4. Click into the field Click here for results. This activates the caclulator. Results are displayed in the fields below.
    1. The Body mass excess, BME is calculated from your height and body mass. Example: 1.1 (With a BME of 1.1 you are 10 % above the reference body mass, which is well within the normal range.) The percentage is calculated as (BME-1)*100.
    2. For comparison with a commonly used index, the Body mass index, BMI is calculated from your body mass divided by your height squared. Example: 21.9 (What does this index tell you?)
    3. The Reference body mass, m° is calculated from your height and shows the corresponding body mass of a person from the healthy reference population. Example: 57.7 (You can compare this reference body mass of 57.7 kg with your measured body mass of 63.4 kg.)
    4. The expected maximum aerobic exercise capacity per body mass, VO2max/m, at a BME of 1.1 is 55 mL·min-1·kg-1. The calculated VO2max/m applies to healthy adults, and does not apply to BME<1.
    5. The Overweight body mass, m+ and Obese body mass, m++ are calculated from the reference body mass. You can compare these limiting values with your actual body mass. Example: 69.2 (Equal or more than 69.2 kg is rated as overweight for a height of 1.70 m with BME=1.2.); 80.8 (Equal or more than 80.8 kg is rated as obese for a height of 1.70 m with BME=1.4.)
  5. If you want to edit your height or body mass entered above, click into the corresponding field, delete the previously entered number, enter the new number, and click into the field Click here for results.

Body mass excess (BME) compared to body mass index (BMI)

  • Balanced standard: BME = 1.0
  • Overweight: BME ≥ 1.2
  • Obese: BME ≥ 1.4
  • For 0.45 to 1.26 m heights (newborns and children), the tables are based on data for WHO Child Growth Standards (WHO Multicentre Growth Reference Study Group, MGRS [8, 9]) compiled from Brazil, Ghana, India, Norway, Oman and the USA, reporting as little as 3 % differences between these groups, and less than 2 % differences between girls and boys.
  • For heights of 1.27 m and above, the tables are based on a Committee on Biological Handbooks data set (CBH [2]), compiled from publications between 1931 to 1944 [3-7]. These agree with WHO MGRS data at heights 1.27 to 1.4 m (children and adolescents) [9] within 1 %, and agree on noting no differences between females and males.
