Here you will find the most up guidance on field and laboratory procedures related to the assessment of Total Energy Expenditure (TEE) as recommended by IAEA. ?Lectures and Expert Working Group reports are included.
This is a concise lecture covering the historical perspectives and principles of energy requirements in humans and how to measure TEE with Doubly Labelled Water (DLW). It covers
This is a consensus report of the International Dietary Energy Consultancy Group (IDECG), published in 1990, covering recommendations on the application of DLW for measuring energy expenditure in humans.
The report discusses isotopic pool sizes and flux rates, estimates of error, fractionation effects, isotope exchange, effects of changes in isotopic background, the energy equivalent of C02, problems of mass spectrometry and problems arising when the method is used in special groups of humans like premature babies and certain categories of hospitalised patients.
This is a report of a Joint FAO/WHO/UNU Expert Consultation held in Rome in 2001. The report presents definition and principles related to human energy requirements and proposes recommendations for various age and physiological groups (infants from birth to 12 months; children and adolescents; adults; pregnancy, lactation and proposes areas for future research.
