There is more medical evidence that pregnant women should steer clear of advice to "eat for two."
Alison Stuebe, M.D. ... reviewed data for more than 1,300 women and found that those who consumed extra calories ... were more likely to gain more than is recommended during pregnancy that's 35 pounds or more for a woman with a normal body mass index, or BMI.

... Several eating habits reduced moms' risk of gaining too much. Women with vegetarian diets in early pregnancy were half as likely to gain an unhealthy amount of weight, and those who exercised vigorously for a half hour a day reduced their risk by 20 percent.
