Use of food quotients to predict respiratory quotients for the doubly-labelled water method of measuring energy expenditure
1986
Black, A.E. | Prentice, A.M. | Coward, W.A.
The use of food quotients (FQ) calculated from dietary records is proposed for predicting respiratory quotients (RQ) that are needed for calculating free-living energy expenditure determined by the doubly-labeled water method which predicts respiratory CO2 production. This approach is based on the fact that, over the relatively long periods of double-isotope measurements (10-20 days), FQ (which can be obtained from a single 4-day measurement of dietary composition) must equal RQ in subjects in energy balance. It is shown that FQ can easily be adjusted to account for anabolism or catabolism for subjects not in energy balance. Typical RQ values are reported for various population sub-groups residing in the United Kingdom (omnivorous adults, vegetarians, vegans, Asian immigrants, and weaned and breast- and bottle-fed infants).(wz)
