I had gestational diabetes and whilst it was a temporary thing (so far anyway as I now have a higher risk of type 2 also) it really did not take long to get in the swing of things. You will quickly work out what works best for you, I found a food diary along with the BSL's made it pretty clear what I could eat! We focussed (as DH had to come for the ride...) on trying to get mostly fresh ingredients and watching my portions, so balancing the protein, carbs etc. Sounds way fancier than it was tho! Also I got really organised with healthy snacks during the day. To be honest I felt amazing in comparison to how I had been feeling. I struggled most with breaky - all the cereals were way to sugary for me, so ended up with porridge and that way great. I also found that adding cinnamon was sposed to be good for regulating BSL's so often added it too porridge, yoghurt etc. It took me ages to get my head around it all too - so well done for getting organised and researching!
