I've been T2 for just under 2 years and I don't test, so wouldn't consider myself an 'expert' on how different food intakes affect one's BG levels. However, I've just embarked on the low carb diet (3 weeks) and if it helps, I rationalised the removal of potatoes, pasta, rice and bread from my diet by considering that they don't really taste of anything, they are just vehicles for the tasty stuff you serve with them. So, just increase the tasty stuff (chilli, bolognaise, stew, casserole) and serve with veg to give it some bulk. And what I've noticed, since taking on this diet, is that my sensitivity to sweetness has increased. I had some French onion soup the other day, homemade, and it tasted as if sugar had been added, although of course none had, it was just the onions somehow (maybe cooking them releases sugars? another thing to learn!). So I think this diet has actually made me more averse to sweet things, which can't be bad. So please, give up the carbs and sweet stuff, start enjoying loads of meat, fresh fish , cheese, veg and salad - it's actually a really enjoyable diet!
