Abstract
The maternal and foetal anabolic phase characterizing pregnancy requires energy storage and hence a state of positive energy balance. Dietary surveys, however, have shown an increase in energy intake during pregnancy of small magnitude only. Furthermore, indirect calorimetry measurements indicate an elevation of basal or resting energy expenditure (EE), particularly during the 3rd trimester of pregnancy. These results are confirmed by measurements performed in a respiration chamber which showed that the rate of 24 hours EE of pregnant women is significantly more elevated in the 3rd trimester than in the nonpregnant state; the latter is explained by a rise of basal EE and to a smaller extent by an increase in energy cost of moving around as a result of the greater body weight. In contrast, when the results are expressed per unit body weight, the difference in 24 hours EE observed during pregnancy disappeared. It seems that energy sparing mechanisms-which are still largely unknown-may come into play during this period: postprandial thermogenesis appears to be blunted during pregnancy. This indicates an increase in net efficiency of food energy utilization. The degree of adaptation of physical activity-which has not been previously investigated-remains a research topic of great interest for the future.
