Calculate Resting Energy Expenditure







Formula

To calculate the Resting Energy Expenditure (REE):

For Males:

\[ \text{REE} = 66.47 + 13.75 \times (W) + 5 \times (H) - 6.76 \times (A) \]

For Females:

\[ \text{REE} = 655.1 + 9.65 \times (W) + 1.84 \times (H) - 4.68 \times (A) \]

What is Resting Energy Expenditure?

Resting Energy Expenditure (REE) is a measure of the total energy required for a person's body to function while resting and doing no activities. This term is sometimes referred to as Basal Metabolic Rate (BMR) or Resting Daily Energy Expenditure (RDEE).

Example Calculation 1

Let's assume the following values for a male:

Using the formula:

\[ \text{REE} = 66.47 + 13.75 \times 70 + 5 \times 175 - 6.76 \times 25 = 1766.72 \text{ kcal} \]

The Resting Energy Expenditure is 1766.72 kcal.

Example Calculation 2

Let's assume the following values for a female:

Using the formula:

\[ \text{REE} = 655.1 + 9.65 \times 60 + 1.84 \times 165 - 4.68 \times 30 = 1396.7 \text{ kcal} \]

The Resting Energy Expenditure is 1396.7 kcal.
