Hello Taz, welcome to the forum. First of all, stop worrying. By joining this forum you will get lots of help and support to get your blood glucose and therefore your risk of complications down.
As a newly diagnosed T2, have you been put on any drugs yet? Or like the rest of us have you been told to go away and try 'diet and exercise' first? Assuming it's the latter (or you're on metformin only), because that's where most of us T2s start, you don't need to eat anything special before exercise. You don't run the risk of hypos (blood sugar dropping dangerously low) if you're not injecting insulin or certain other glucose-lowering drugs.
As for the rest of your diet, here are some things that work for me to reduce carbs: I only ever buy small (400g) loaves of wholemeal bread, and only a max of 2 slices per day. I only have 1-2 250g jacket potatoes a week, and a max of 50g dry weight of rice/pasta/couscous per day. Mashed cauliflower makes a really nice topping for shepherds pie. I eat lots of veg with my dinners, to replace some of the plate space that would have been taken up with carbs. Snacks are mostly fruit. Breakfasts can be difficult, but I usually have a Mullerlight yogurt with ONE Weetabix or 15g of Grape-Nuts stirred in. Weekend breakfasts are scrambled egg with lean bacon, low fat sausage, tinned toms, mushrooms and a few baked beans (no toast).
If you've been told to lose weight, have a look in the Weight Loss forum and post any questions about what's worked/working for us.
