This study will examine the safety and effectiveness of a dietary intervention in pregnant women. Women who are obese will be invited to participate. The control arm will receive routine prenatal care and one in-person nutritional and dietary counseling session to promote healthy eating during their pregnancy. The intervention arm will receive a more intensive dietary program that will include in-person counseling and group support sessions. The goal of the intervention will be weight maintenance (weight at 2 weeks after delivery should be within 3% of baseline weight) and avoidance of postpartum weight retention

Primary Outcome Measures:
  • Maternal Weight Change [ Time Frame: baseline to 2 weeks post partum ]
    We chose the weight at 2 weeks postpartum, rather than at an end point during pregnancy, to avoid the contribution of products of conception, maternal edema, and increased maternal blood volume to the weight gain.

Secondary Outcome Measures:
  • Pregnancy Weight Change [ Time Frame: baseline to 34 weeks gestation ]
  • Large for Gestational Age (LGA) [ Time Frame: At birth ]
    Large-for-gestational-age defined as weight greater than the 90th percentile for gestational age at birth.
