Resting Energy Expenditure (REE)

Definition

Resting Energy Expenditure (REE) is the amount of energy your body needs to maintain basic physiological functions at rest, like breathing and circulation.

Scientific / Technical Definition

Resting Energy Expenditure (REE), also known as Resting Metabolic Rate (RMR), represents the energy required by the body at rest to sustain the vital functions, including heart rate, respiration, neural functions, and temperature regulation. REE accounts for the largest portion of daily energy expenditure and varies depending on factors such as age, sex, muscle mass, and overall health.

Benefits

Helps determine daily caloric needs.
Assists in designing personalized diet plans.
Important for managing weight and nutritional needs.

Examples

Calculating REE using equations like the Harris-Benedict equation.
REE measurement through indirect calorimetry.

Additional Information

Importance: Resting Energy Expenditure is important for understanding how much energy your body needs to function at a basic level, which helps in managing dietary intake and energy balance.
