The doubly labeled water method

The doubly labeled water method is particularly useful for measuring average metabolic rate (Field metabolic rate) over relatively long periods of time (a few days or weeks), in subjects for which other types of direct or indirect calorimetric measurements of metabolic rate would be difficult or impossible. … See more Doubly labeled water is water in which both the hydrogen and the oxygen have been partly or completely replaced (i.e. labeled) with an uncommon isotope of these elements for tracing purposes. In practice, for both … See more The technique measures a subject's carbon dioxide production during the interval between first and last body water samples. The … See more Doubly labeled water may be administered by injection, or orally (the usual route in humans). Since the isotopes will be diluted in body water, there is no need to administer them in a state of high isotopic purity, no need to employ water in which all or even most … See more WebAug 1, 2013 · The doubly labeled water (DLW) technique is used to assess metabolic rate (MR) in free-living conditions. We investigated whether differences in the nutritional and body adiposity status affect validity of the assessment of CO 2 production (rCO 2) by the DLW technique.
