Hello Captain Crunch and welcome.
The first rule to take on board is Don't Panic! You've taken the first step and found this forum and were motivated to post.
Practically everyone on here was diagnosed and faced the worry same as you. you will find that there is a huge wealth of knowledge and experience on here along with multiple ways to get your numbers down.
You need to know your numbers, if you don't have them tell your GP surgery you need them. It can help to sign up online with your surgery so that you can see your results quicker despite GPs and DNs saying the results will take a week to come back mine are available on line the next day.
Test results mean nothing unless you know what your BG is every day. Some GP surgeries will give or loan you a BG monitor and you should have lancets and testing strips put on repeat along with a yellow sharps disposal box. I bought my meter and my GP put the lancets, strips and box on repeat.
You need to test before and two hours after eating and record what you ate and what the readings are. Over time you will be able to see what spikes your BG and what doesn't. We are all unique, potatoes don't hugely spike my BG but carrots do. You have no way of knowing unless you test.
You didn't become type 2 overnight and you won't unless you're very lucky get your numbers down overnight. It takes time and without knowing what individual foods do to your BG you can't get a handle on things.
Most of us on here follow LCHF with varying amounts of carbohydrates, from practically none up to around 100. I keep mine between 50 and 80 g a day. That suits me, in three and half years I've lost over seven stones and my numbers steadily decrease. I keep to my LCHF 95% of the time. I can be 100% for weeks but I'm human I can fall off the wagon for one meal or one snack but then get straight back into plan. You do not fail if you get back onto LCHF again.
Make
www.dietdoctor.com your friend put any foodstuff into search and you will find suggestions or reasons why it's not a good idea. There are recipes there for all sorts of things including chocolate fudge which is my favourite at the moment. You do have to pay to access after a free trial but I think it's worth it. There's meal plans, video, research results on there.
