Pregnant women operate at 2.2 times their BMR — almost the maximum possible, every day, for some 270 days, researchers found. A rate much higher than that and pregnancy would be unsustainable, damaging to the body and potentially deadly.
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.
Do you burn more energy when pregnant?
It would make sense, too, that people who are pregnant and lactating only burn about twice as much energy as they normally would, instead of the 2.5 times like the athletes did. Unlike athletes in endurance competitions, who are trying not to lose weight, people who are pregnant have to gain weight.
How much energy does a pregnant woman need in kJ?
In the second trimester, the energy requirements increase by about 1,400 kilojoules per day (or 300 calories). That’s the equivalent of a small tub of yoghurt and a banana. For the final trimester, the energy requirements increase again, by a total of 1,900kJ a day above pre-pregnancy requirements.
How much harder does a pregnant woman’s body work?
You produce more blood

Why does a pregnant woman need energy?
Extra dietary energy is required during pregnancy to make up for the energy deposited in maternal and fetal tissues and the rise in energy expenditure attributable to increased basal metabolism and to changes in the energy cost of physical activity.
How do you calculate total energy needs?
There are several methods for calculating energy needs. A simple method is to take the athlete’s weight (in pounds) multiplied by 10 for a rough average of basal needs, or basic needs without any exercise. Then, add in an activity factor and an average of calories burned for every minute of exercise.
