Gestational diabetes (GDM) imposes an inequitable disease burden for Maori and Pacific Island women and their newborns. The higher rates of overweight and obesity in this population increases the risk of developing GDM and GDM increases the risk of developing type 2 diabetes for women post-partum and in their offspring. Limiting excessive weight gain during GDM is likely to improve these health outcomes and could be achieved by following a reduced carbohydrate diet. Social determinants can impact health outcomes and need to be considered with adherence to nutrition interventions. Reduced carbohydrate diets can be more costly, and this could impact adherence to the diet. This study aims to investigate (1) if providing fruit and vegetables to the participant at no cost, would increase adherence to a reduced carbohydrate diet in GDM and (2) whether the micronutrient intake is maintained when following a reduced carbohydrate diet.
