Validated predictive equations are used by professionals to determine the body composition of patients or to determine nutritional requirements. So, Nutrium has integrated several predictive equations to make calculations easier and more intuitive for nutrition professionals.

In the page **"Measurements"** of the appointment layout you will find equations to determine body composition.

For **body fat mass**:

- Peterson Equation;
- Evans Equation;
- Durnin and Womersley Equation;
- Jackson and Pollock Equation (3 Skinfolds);
- Jackson and Pollock Equation (7 Skinfolds);
- Guedes equation;

For **bone mass, muscle mass, and residual mass**, respectively:

In the **"Planning" **section** **of the appointment layout you will find equations to make dietary recommendations. Such as:

- Recommended body weight by J.D. Robinson;
- Recommended Body Fat % by Lohman TG.

Equations to determine the client's **basal metabolic rate**, such as:

- WHO Equation;
- Harris-Benedict Equation for the general population
- Harris-Benedict Equation Revised calibrated for obese people;
- Mifflin St. Jeor Equation for the US;
- Katch Mcardle Equation for college men and women;
- Cunningham Equation (includes fat-free mass variable);
- Henry Equation for the UK;
- Black et al. equation for the French population;
- Ten Haaf Equation (weight) for athletes;
- Ten Haaf Equation (lean body mass) for athletes.

Equations to determine **daily energy expenditure**:

- EER, IOM 2005;
- BMR x PAL.

For **nutrient recommendations** you will find two accredited sources:

- Food and Nutrition Board/IOM;
- Scientific Advisory Committee on Nutrition;
- ANSES, 2016

To determine the **energy spent during specific physical exercises**:

- Metabolic Equivalents (METS).

These predictive equations will allow you to **determine the body composition and nutritional needs of patients quicker and with more precision**. Let us know if you use other equations in your daily work.
