How to calculate the PAL with METs in Nutrium

Have you checked our recent updates for Sports Nutrition? We have a new update!

Calculating the physical activity level (PAL) through metabolic equivalents (METs) can make all the difference when assessing daily energy requirements (DEE) and now you can calculate these automatically with Nutrium.

Let's learn more about this in the article below.


Why is this feature important?

A MET is a numerical value that represents a multiple of the resting metabolic rate for a particular activity.

This value applies to the level of energy expenditure achieved during the performance of a specific activity at a designated intensity and provides a way of expressing the total caloric cost of the activity.

The PAL provides information about the duration and intensity of a set of different activities performed during a 24-hour period and the relative differences in usual levels of physical activity.

The relationship between METs and PAL is such that each physical activity performed in a 24-hour period is assigned a MET value based on its intensity and duration.

A resulting set of MET values is subsequently used to calculate the PAL for determination of the PA needed to estimate the total energy expenditure. (1)

How to calculate the PAL using METs

On the Planning tab, you can choose a new option on the section Physical Activity Level - Calculate PAL.

When selecting this new option, a new box will be featured and you will have a list of the most common activities, like sleeping, taking a shower, driving and a place to add the duration of each of them.

To complete the 24-hour period you can add new activities reported by the client during the consultation, such as physical activities and their duration.

When the 24-hour period is complete a sum of all METs will show as well as the physical activity level.

This new feature is useful not only to your nutrition clients who are athletes but also to be able to assess with more accuracy all your clients' PAL.
