The doubly labelled water (DLW) method is the only international standard method able to measure with high precision the amount of energy expenditure of a subject under free-living activities, using oxygen-18 and heavy water. Taiyo Nippon Sanso Corporation has supported the spread of DLW and researchers around the world through long-term supply of the stable isotopes (Water-18O and D2O). In 2021, the results of an international research project into energy expenditure supported by the International Atomic Energy Agency were reported in the prestigious global academic journal Science (August 13, 2021 edition), further highlighting this work.
