Basal Metabolic Rate measures the calories consumed by a human at rest per day.

The Basal Metabolic Rate depends on many variables. An empiric model that it is widely used for a first estimation depends on.

The BMR for males is

\[ BMR (cal/day) = 10 * weight (kgr) + 6.25 * height (cm) \\- 5 * age (years) + 5 \]

and for females

\[ BMR (cal/day) = 10 * weight (kgr) + 6.25 * height (cm) \\- 5 * age (years) - 151 \]

-Greater for males -Increases with weight and height -Decreases with age

We used shinny to build a BMR Calculator. The types of widgets that we use are

Numeric Input: Three numeric inputs are needed for the values of height, weight and age.

Select Input : One additional input is needed to specify the gender.

We added also the tabs in the UI:

BMR: It displays the predicted BMR index

Info: We add information about the App and the BMR index.

You can find the App in the shinny server by following the address:

The code for the App is in my Github repo:

Where you can downlod the ui.R and the server.R files to run the app in you IDE.
