Hi
@Woodside , welcome to the forum. Often with T2 it is not so much that the pancreas is not producing enough insulin , it’s more that that the pancreas is trying to produce much more insulin because the insulin for some reason can’t unlock the cells to allow the glucose to enter the cells where it’s needed to fuel the body, so the glucose builds up in the blood instead .
Quite a few people have no symptoms of diabetes and only find out while being tested for other things.
Yes lowering carbohydrate intake esp the starchy (fast acting) carbs is the way to go. Other things to be aware of are that some things that are considered healthy may not be suitable for T2s, ie fruit juice , it’s packed full of fructose, or high in carbs,grapes are little sugar bombs, smoothies , many breakfast cereals.
And some things that are considered unhealthy are actually quit good for us , ie a cooked breakfast, minus the potato products, bread and baked beans .
We often have no problems with protein in all it’s firms or good fats.
Just to make things interesting

we are all different in what and how many carbs our bodies can tolerate , so we advise self testing to find this out, ie T2s are often told porridge is a good breakfast , but for some it isn’t and without testing you won’t find this out easily.Many here use the
Gluco navii meter and it’s test strips as you have to watch out fir the cost if the test strips, £8 for a pot of 50 for this meter, many others use strips that cost over £15 for 50 and when you are initially doing in depth testing directly before eating then 2 hrs after the first bite, cost is important , many also test i. Waking and going to bed.
You are looking for no more than a 3 or 4 mmol post meal increase.
In time your pre meal levels will start to decrease.
Its a good idea to keep a food diary with a BG (blood glucose) log.
I invested in a flat bed kitchen scale that I could Zero and add more items.
