Resting Energy Expenditure PROTOCOL

The resting energy expenditure (REE) represents the amount of energy expended by a person at rest. Basal metabolic rate (BMR) is more precisely defined as the REE measured just after awakening in the morning. In practice, REE and BMR differ by less than 10% so the terms can be used interchangeably. • REE is measured by indirect calorimetry.
