WebThe DLW method is based on the differences in turnover rates of 2 H 2 O and H 218 O in body water. The DLW technique has been validated against IC and is now considered to be a gold standard for measurements of TEE under free-living conditions. 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.
WebOct 27, 2024 · A technique of long standing called the doubly labeled water (DLW) method is a powerful tool for nutrition and metabolic studies, giving an estimate of total energy expenditure (TEE) in free-ranging subjects ( 1–5 ). WebThe doubly labeled water method was compared with indirect calorimetry and a nutrient-balance study for simultaneous determination of rates of CO/sub 2/ production, energy expenditure, and water intake over 5 days in four preterm infants. Additionally, metabolizable energy (ME) intake estimated using the isotope procedure (as energy expenditure ...
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 WebApr 27, 2024 · Kevin D Hall, Juen Guo, Kong Y Chen, Rudolph L Leibel, Marc L Reitman, Michael Rosenbaum, Steven R Smith, Eric Ravussin, Methodologic considerations for measuring energy expenditure differences between diets varying in carbohydrate using the doubly labeled water method, The American Journal of Clinical Nutrition, Volume 109, …
WebSep 17, 2012 · Doubly labeled water (DLW) is currently the most widely used and well accepted biomarker. DLW provides an accurate measure in free-living subjects of their total energy expenditure, which is equivalent to energy intake in weight-stable people.
