An Early-customized Low Glycaemic-index (GI) Diet Prevents LGA Babies in Overweight/Obese Pregnant Women

High pre-pregnancy body mass index (BMI) and excessive gestational weight gain (GWG) are associated with many unfavourable maternal and neonatal outcomes. Adherence to lifestyle recommendations could be a major determinant of the efficacy on preventing unfavorable outcomes, namely among overweight/obese women.

This study aimed to determine whether the prescription of a lifestyle program, consisting of a customized low-glycemic index (GI) diet and a physical activity program, in overweight and obese women could affect the occurrence LGA babies. It also aimed to determine whether this kind of prescription influences the adherence to healthier eating habits, and how this, in turn, can influence the occurrence LGA.
