Resting metabolic rate testing measures how much energy your body uses at rest. You lie or sit quietly and breathe into a mouthpiece or under a hood while a machine reads the oxygen you take in and the carbon dioxide you breathe out.
A formula or a fitness tracker can only estimate this number, and estimates can be off for any one person. Clinics use the measured figure to set calorie and nutrition targets. It describes your body on the day of the test.

How do I prepare?
Clinics usually ask you to come in without eating, without caffeine and without exercising beforehand, because all three raise the number. Follow the clinic’s own instructions.
Will my result change?
It can. It moves with changes in muscle, weight and activity, so some people retest after a change in training or diet.
