BMI stands for Body Mass Index and is a measurement in kg/m2 utilized by medical professionals to determine healthy body mass levels.

Weight Calculations



% Weight Change (%WC)



How much weight you have gained or lost, as a percentage.











Desirable/Ideal Body Weight (DBW / IBW)



A dietetic calculation of how much you should weigh based on your height and biological sex.












% Desirable/Ideal Body Weight (%DBW / %IBW)



The percentage of your body weight relative to your ideal weight.
Less than 100% means you are below your ideal weight.
Above 100% means you are above your ideal weight.












% Usual Body Weight (%UBW)



The percentage of your body weight relative to your usual weight.
Less than 100% means you are below your usual weight.
Above 100% means you are above your usual weight.












Adjusted Desirable/Ideal Body Weight
(Adj DBW / Adj IBW)



Used by hospital dietitians when BMI is ≥ 30.0 or %DBW is ≥ 130.0 %.

Protein Calculations





Input the desired protein quantity in g/kg below and corresponding equivalencies will be calculated based on your anthropometric data inputs. % Protein is based on the median caloric requirement from the Custom Calorimeter above. Adjusted values selected above will register for the protein calculations once the calculate button is clicked below.

Although protein is essential in every diet, clinicians should not prescribe the consumption of processed meats, which are classified as Class 1A Carcinogens by the World Health Organization's IARC, or International Agency for Research on Cancer. The IARC made this conclusion after reviewing over 800 relevant studies. This includes bacon, hot dogs, ham, sausages, beef jerky and others - all of which may cause colorectal and other cancers via the N-Nitrosamine and Heterocyclic Amine pathways, among others.3,4,5

DIETETIC INFORMATICS

Mifflin St. Jeor Calorimetry



An equation predictive of Resting Metabolic Rate (RMR), also known as Resting Energy Expenditure (REE), which is measured in kcals.
This is how many calories your body uses at rest.

Note: Discrepancies may be present when comparing this calculation to those in the Macronutrient section because of differences in scope of practice. Mifflin St. Jeor Calorimetry is based on a specific, evidence based formula which factors in physical activity in addition to gender, while the Macronutrient calculations are based on formulae that dietitians use on a regular basis to determine individual needs independent of physical activity.











Revised Ireton-Jones Equation (1997)



An equation developed for calculating energy expenditure in patients with specific circumstances. Select those circumstances below and then press calculate.














Heavy Spontaneous Breathing







Ventilator Dependency and Critical Care









Free Water Deficit



An equation used to estimate the volume of water in liters (L) required to quench dehydration during the initiation of fluid-replacement therapy. Only administer half of the calculated fluid supply in the first 24 hours and the other half during the next 24 hours.
