The Resting Daily Energy Expenditure  (RDEE) formula computes the base daily rate of calorie consumption when at rest.  

INSTRUCTIONS: Choose units and enter the following:

• (LBM) - Lean Body  Mass

Resting Daily Energy Expenditure (RDEE): The calculator returns the energy in food calories (kcal).

The Math / Science

The formula for Resting Daily Energy Expenditure is based on the Katch-McArdie equation as follows:

   `RDEE = 370 + (21.6 * LBM)`

where:

• RDEE = Resting Daily Energy Expenditure
• LBM = Lean Body Mass
