The healthcare providers in this study will be Registered Dietitians (RD). The intervention RD will be trained in Healthy Conversations, a supportive method of communication that utilizes open-ended questions to support patient-centered behaviour change. This allows women to explore health issues, identify barriers and discover solutions for improving their own health. This supportive prenatal counselling will occur with the intervention group concurrently while completing lifestyle questionnaires with the study RD. During these conversations, health goals will be made and will be followed up at future visits. The control group will complete the lifestyle questionnaires with the control RD; they will not receive additional lifestyle support at these visits. Women will be randomized into one of the two study groups and will be blinded to their study allocation. All participants will complete two in person visits and two follow-up telephone calls. Data will be collected on diet, physical activity, gestational weight gain, delivery, and infant outcomes.
