Resting Energy Expenditure

Definition

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

Scientific / Technical Definition

Resting Energy Expenditure (REE) refers to the minimum energy required by an individual's metabolism to perform essential activities such as cellular metabolism, thermoregulation, and functioning of vital organs, measured under resting conditions while the individual is awake and in a post-absorptive state.

Benefits

• Understanding REE can help in formulating effective weight management and nutritional plans.
• Knowing one's REE contributes to the design of personalized dietary and fitness regimens.
• Monitoring REE is important for clinical assessments in conditions that alter metabolism, such as thyroid disorders.
