Women Eat More When Pregnant With Boys

June 07, 2003|From Times Staff and Wire Reports

Women pregnant with boys tend to eat about 10% more calories a day than those carrying girls but don't gain more weight, researchers from Harvard University and the Karolinska Institutet in Sweden reported in this week's British Medical Journal.

The study appears to explain -- at least in part -- why newborn boys are heavier than girls and suggests that signals between the fetus and the mother drive the appetite during pregnancy.
