Summary

This study looked at whether women with different types of gestational diabetes respond differently to meals with varying amounts of carbs, protein, and fat. Nineteen women with gestational diabetes wore a continuous glucose monitor and ate two test meals. The goal was to see if matching meal plans to a woman's specific diabetes subtype could help control blood sugar better.
