basal metabolic rateA baseline rate of metabolism expressed as O2 consumption or heat production under resting or at basal conditions, usually measured long after eating.
The BMR may be calculated with a formula for calculating a person’s proteo-caloric requirements; BMR is measured under basal conditions—12 hours after eating, after a night’s sleep, no exercise or activity preceding test, without emotional stress and at a comfortable temperature. BMR is increased in hyperthyroidism and decreased in hypothyroidism.
The most commonly used formula for calculating BMR is that of Harris and Benedict:
BMR, Male= 66 + (13.7 x Wt) + (5 x Ht) – (6.8 x age)
BMR, Female: 655 + (9.6 x Wt) + (1.8 x Ht) – (4.7 x age)
