Medical nutrition therapy based on the control of the amount and distribution
of carbohydrates (CHO) is the initial treatment for gestational diabetes mellitus (GDM), but
there is a need for randomized controlled trials comparing different dietary strategies. The
purpose of this study was to test the hypothesis that a low-CHO diet for the treatment of
GDM would lead to a lower rate of insulin treatment with similar pregnancy outcomes compared
with a control diet.
