Welcome to the forum

The really tricky thing is that blood glucose responses to various foods are highly individual, and it can be impossible to say which types and amounts of carbohydrate will ‘spike’ your BG without checking for yourself.
While there are obvious things like cakes, biscuits, sweets and sugary drinks that you will be wanting to cut out straight away, you might be surprised how much *all* carbohydrate affects your BG levels, including rice, pasta, bread, pastry, grains, cereals and many fruits.
Many forum members use a BG meter, and take a reading before and again 2hrs after eating, to see what the effect of a meal or snack was on their blood glucose levels.
Once you can see how you respond to different meals you can begin experimenting with reducing amounts of carbs and trying different types (sometimes just having things at a different time of day makes a difference).
If you are interested in this approach you may find
test-review-adjust by Alan S a helpful framework.
If you need to self fund your BG meter (many GP surgeries don’t routinely offer them to T2s unless they are on certain meds), the most affordable meters members here have found are the
SD Gluco Navii or the
Spirit Tee2 - which both have test strips at around £8 for 50
Good luck, and let us know how you get on
