`"TDEE" = BMR("female", "w" , "h" , "a" ) * ActivityLevel("moderate")`

Enter a value for all fields

The **Total Daily Energy Expenditure** calculator computes the daily calories burned by a person based on their Basal Metabolic Rate and their level of activity.

**INSTRUCTIONS:** Choose units and enter the following.

- (h) height
- (w) weight
- (a) age
- (g) gender
- (AL) Activity Level

**Total Daily Energy Expended(TDEE):** The calculator returns food calories per day (kcal). However, this can be automatically converted to compatible units via the pull-down menu

The **Total Energy Expenditure** formula is as follows:

TDEE = BMR * AL-Factor

where:

- TDEE = Total Daily Energy Expended
- BMR = Basal Metabolic Rate
- AL-Factor = Activity Level Factor

The Activity Level Factor is as follows:

- sedentary: 1.2
- light: 1.275
- moderate: 1.55
- very active: 1.725
- extremely active: 1.9

The **Base Metabolic Rate (BMR)** formula computes the daily calories consumed by a person at rest based on their gender (**g**), age (**a**), weight(**w**) and height (**h**). The formula is based on the Mifflin St Jeor equation.
