Most people are told to eat lots of carbs and that they will be given the drugs to deal with the consequences. This is certainly one approach and, I note you are on metformin and gliclazide.
However, many on this forum and elsewhere prefer to try and reduce their sugar levels and drug intake by reducing carb intake. Some find they need or want to reduce more than others. If you want to low carb (and you may HAVE to reduce your gliclazide intake to do this safely) you should reduce/give up potatoes, pasta, cereals, bread and other flour produce and rice. You also need to give up all sugary things e.g. cakes, biscuits, sweets, sugary drinks, honey and, perhaps surprisingly most fruit and fruit juices.
Some say that wholemeal bread/ pasta etc is OK for them, others avoid it all.
The best way to find out what suits you is to test before and after every meal, to find out what different ingredients and combinations of ingredients do to you. Your diabetic nurse will, very probably be against you testing yourself - ignore her/him!
It is worth doing. Many T2's have reduced their sugar levels and HbA1c to normal non-diabetic levels and given up all diabetic drugs by low carbing - you could become one of them. Note that, as you are already an ideal weight, you will need to make up the loss of calories with more fats, e.g. cheese, cream, eggs.
Best of luck and do ask as many questions as you need to.
