You can have sugar free drinks, don't despair!
You need carbs but just less of them.
Aim for your dinner plate to be half veg, green veg best, avoid carrots. Lots of protein & for me 30 - 40g of carbs though you'll have to test to see what you can handle.
Basmati & brown rice good. Obviously brown pasta too.
I can handle around 3 to 4 small salad potatoes. Eat the skin with potatoes, sweet potatoes especially as full of fibre which helps.
I found Burgen soya & linseed bread the best.
For breakfast, I could have 2 slices with eggs & a glass of wholemilk. On my first pregnancy though I couldn't tolerate milk as the lactose sugar made my scores high so again you'll have to test as you go.
For lunch, another 2 slices with cheese, ham & mayo.
Get rice or corn cakes high in fibre & smother with peanut butter. But you gotta make sure peanut butter is right. In Ireland, we seem to have better choices regarding this but go on gestationaldiabetes.co.uk & search what is best in Britain.
Stick to berries for fruit, blueberries are great, raspberries & strawberries, you can add natural yogurt (provided its under 5 g of sugar) or even double cream for a treat.
Add nuts like walnuts for a change.
If you eat an apple, pair it with peanut butter.
Actimel 0% are fine as a snack with some cheese. Babybels can be handy.
So much advice you read online is awful, nature valley bars are often cited, they are still way too high in sugar, remember aim for 5g sugar or less per 100 grams.
You'll become a nutritional expert reading all the labels whilst shopping.
Again in Ireland we have sugar free brands that I'm not sure if they're available in Britain but 'free'ist' do sugar free cookies etc & yes although instead of natural sugar they are artificial sugars, if you can find these eat them, it's going to be for a short period & you'll need a fix. Also Spanish brand Gullon sell sugar free biscuits, just keep testing as you go.
It really is a pain in the neck, going out to cafes or restaurants becomes a challenge.
Popcorn & salted peanuts in moderation become a nice snack.
Honestly it's a reason while I'll probably stick to just 2 kids, I absolutely hate the diet. It's something to just get through. I just can't wait to eat normally again, best of luck.
