DLW stands for doubly labeled water, a method for measuring energy expenditure that involves drinking water that has been labeled with isotopes (hydrogen-2 and oxygen-18) and then follow-up measurements of those isotopes in urine or blood samples. This method is considered the gold standard for measuring energy expenditure outside of a laboratory setting and involves following subjects for a one- to two-week period. DLW (doubly labeled water) involves administering a dose of water that is labeled with stable isotopes and then monitoring the rate of disappearance of these isotopes from the body over the course of one to two weeks. This allows for an estimate of energy expenditure over that time period.
