My suggestion would be sticking to a balanced diet. With five food groups and steer away from processed sugars including take away food. Maybe limit your fruit intake to 2 pieces a day.

I wanted to avoid GD early in my pregnancy so I have seen a nutrition and these were her recommendations.

A good low sugar cereal breakfast consists of toast, cereal (weet-bix). Morning tea can be a yoghurt or fruit or crackers. Lunch a Sandwich meat / salad etc. Afternoon Tea like morning tea. Then dinner with protein (meat/eggs/fish) and vegetables. Make sure you also have milk/cheese.

This should definitely help your sugar levels. If you get the cravings drink water.

Goodluck. I got sent for the second test in first pregnancy and I was fine. I must have just had high sugar that morning of the other test.
