It is testing the way your body responds to sugar and not having sugar (or having lots of sugar) for x amount of time before the test does not alter the result... I still don't know/understand how it works, but that's what my doctor said. (although I had been eating low carb for over 7 months with my 1st pregnancy and 2 years with my second pregnancy and throughout the pregnancy and both times I didn't get GD but got told my results were exceptionally good).
