Abstract
To evaluate the adequacy of meal rations in providing calories for military personnel during Arctic training, energy balance was studied in a group of infantrymen during a field exercise near Iqaluit on Baffin Island. Energy expenditure was determined over 9 days in 10 individuals using doubly labelled water. Six additional subjects served as controls to examine baseline isotopic enrichment shifts due to geographical relocation. Complete food records were also collected from 20 individuals and caloric content determined. Average energy expenditure levels, corrected for shifts in baseline isotope levels were 4179(SD 988) kcal/day. IMP rations were calculated to provide 4350 kcal/day. Higher energy expenditure levels compared with reported intakes, at relatively constant body weight and energy balance, suggests (i) significant underreporting of food intake by subjects, and (ii) that energy needs of most subjects were being largely met by rations and supplements.
