Study goal is to determine whether behavioral lifestyle intervention during pregnancy can reduce the number of women who exceed the Institute of Medicine recommendations for weight gain during pregnancy.

It is hypothesized that the intervention will reduce the number of women who exceed weight gain guidelines relative to standard care. The investigators also expect the intervention to reduce the proportion of women exceeding weight gain guidelines in both normal weight and overweight groups.
