TAIYO NIPPON SANSO -The Gas Professionals-

～ For Total Energy Expenditure(TEE) measurement ～

TEE(Total Energy Expenditure) of humans or animals can be measured by administering DLW to experimental subjects and following the differential loss of Deuterium and Oxygen-18 isotopes from the body.

Overall precision (about ±5%, depending on circumstances)
Cross-validated against whole-body calorimetry
Free-living condition with minimal interference
From infants to the aged
Not need expensive experimental facilities
Simultaneous measurement of TBW(Total Body Water)

Obesity study: Judgment of overeating → Diabetes, heart disease...

Athletes study: Development of systematic weight-loss program
TEE determination of various kind of training
