Why do pregnant woman need more energy and protein than non pregnant woman do?

Pregnant women require more energy and protein to support the growth and development of the fetus, as well as to accommodate the physical changes occurring in their own bodies. Increased caloric intake helps meet the demands of the developing baby, while protein is essential for building tissues, organs, and the placenta. Additionally, the body’s metabolic rate rises during pregnancy, necessitating higher nutritional intake for overall health and energy levels.
