How much energy does a pregnant woman use?

On the basis of theoretical calculations, recommended allowances for energy intake during pregnancy have been set at 200 to 300 kcal/day (FAO/WHO/UNU, 1985; NRC, 1989) above nonpregnant levels; however, few dietary studies of pregnant women corroborate increments of this magnitude.
