Hi Lady,
I haven't had my GD test yet and I didn't have it during my first pregnancy however for some reason I am paranoid about having it this time so I have adopted a diabetes diet and have been following that as I believe it's a healthy way to eat anyway. An example day for me is as follows:
Breakfast - 2 boiled eggs & half wholemeal english muffin with nut butter
Snack - 1 cup low fat natural yoghurt with strawberries and chia seeds (optional)
Lunch - Salad with tuna - spinach leaves, feta, cucumber, cherry tomatoes, capsicum, baby beetroot, onion (whatever vegetables you want really)
Snack - carrot sticks, celery sticks, capsicum sticks with hommus
Dinner - any lean meat with steamed vegetables
Hope this helps xx
