Resting Energy Expenditure Calculator

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:

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

Where:

\(\text{REE}\) is the resting energy expenditure (kcal)
\(W\) is weight (kg)
\(H\) is height (cm)
\(A\) is age (years)

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:

Weight (\(W\)) = 70 kg
Height (\(H\)) = 175 cm
Age (\(A\)) = 25 years

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:

Weight (\(W\)) = 60 kg
Height (\(H\)) = 165 cm
Age (\(A\)) = 30 years

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.
