Strict diet with no cause ?

Ellen • Love my baby

Today I went for my 6 week appointment (and the baby was so dang cute !! )

But while I am overweight , I am not diabetic in anyway . I was basically told that I have to eat strict as if I am a diabetic and avoid sugars and carbs and such . I want to prevent prenatal diabetes which I have been cutting back on sugar and working out more even prior to pregnancy. But now I am afraid to eat stuff ... what do you think about this . Anyone out there with a similar experience ?
