Pregnancy: Eating for Two Not a Good Idea

Gaining some weight during pregnancy is healthy, but a new study shows that one-third of new mothers whose weight was normal before pregnancy were overweight or obese a year after childbirth. The investigators from the University of Chicago drew on data from 774 low-income women. The participants were interviewed three times in the year following childbirth, and the women's height and weight were measured at six and 12 months after delivery. The researchers reported that their study participants gained an average of 32 pounds during pregnancy and that about 75 percent of the women remained heavier a year after their babies were born than they were before pregnancy. When interviewed a year after their babies were born, 47 percent of the women still weighed at least 10 pounds more than they did pre-pregnancy. Experts note that breastfeeding and moderate exercise can help with weight loss after pregnancy. Study leader Loraine K. Endres, M.D., made the point that "eating for two" should not be interpreted to mean doubling caloric intake. She said that pregnant women should consume only 300 to 400 extra calories per day as long as they're expecting only one baby.
