Healthy Eating in Women at Risk of Gestational Diabetes

4 individual 1-hour in person (or virtual, according to potential public health restrictions and patients' preference) motivational interviews (12, 18, 24 and 30 weeks) with a registered dietitian will be conducted to elaborate S.M.A.R.T. (Specific,Measurable, Attainable, Relevant, Timely) goals regarding diet, based on the 2019 Canada's Food Guide. Between those individual follow-ups, 4 phone calls with the registered dietitian will be provided (15, 21, 27, 33 weeks). Throughout the study, 10 informative nutritional video clips will also be provided. Participants receiving the intervention will have access to an online Facebook private community to discuss and share experiences, thus maintaining motivation and providing social support.
