Longitudinal assessment of energy expenditure in pregnancy by the doubly labeled water method

GR Goldberg, AM Prentice, WA Coward… - The American journal of …, 1993 - Elsevier
Twelve women were studied before pregnancy and at 6-wk intervals from 6 to 36 wk
gestation. Total energy expenditure (TEE) by the doubly labeled water method, basal
metabolic rate (BMR), energy intake, and body composition were assessed on each
occasion. There was substantial interindividual variation in the response to pregnancy.
Mean total energy costs were as follows: Δ BMR 112±104 MJ (range− 53 to 273), Δ TEE
243±279 MJ (range− 61 to 869 MJ), and fat deposition 132±127 MJ (range− 99 to 280 MJ) …
