Welcome to the forum
@Kavb
Sorry to hear about your diagnosis.
Yes, you are quite right, it is the total carbs that you need to be aware of, not just the ‘of which sugars’ as the body is very efficient at breaking down carbohydrate pretty speedily whether it is white, brown or whatever. Some people have more success with wholemeal and seedy versions, but for others it makes little difference - the most important thing is to establish your own tolerances and develop a way of eating that suits you.
This may sound daunting at first, but many people later reflect that they really enjoy their new way of eating with a huge variety of flavours and none of the ‘beige padding’.
Adjusting to a lower carb higher fat menu can take a bit of rethinking, but members here will be on hand with a wide variety of approaches and ideas from moderate 150g-a-day, down to very low carb / keto type approaches of 60g of carbs a day or less.
Some meals can be quite readily adapted - there are lower carb alternatives to rice which you can make out of cauliflower grated and *just* cooked, or mashed with butter and cheese to top a shepherd’s pie. Many of the carb elements to dishes are mostly there to provide a transport for the sauce and flavour, so some things will be a bit like switching to vegetarian alternatives to mince... the new dishes aren’t 100% identical, but they are still really enjoyable, and most of all if they keep your BG in check they are
much better for you.
There are crustless ‘fathead’ low carb pizza bases, and the meat part of a kebab will be fine for your BG (though you may have to be a little restrained if you have a few pounds to lose)
There are quite a few ideas this section of the forum - perhaps have a browse through a few pages of ’what did you eat yesterday’ to see what lower carb options others are choosing.
Also consider getting a Blood Glucose monitor so that you can see quite how your metabolism and gut biome responds to the food you are eating.
Some people find before-and-2hrs-after pairs of readings along with a food diary (ruthlessly honest!) are a great first step.
Good luck, and let us know how you are getting on, and if there are any padticular meals/dishes that you are struggling to adapt.
