I really have no idea as I was just told change of lifestyle and avoid all sugars and sweeteners as I'm only pre D. My gp wants me back for a re test on hba1c in july
Okay, then... With prediabetes you might not have to go as far as a keto diet, and moderately low carb could be alright. To be sure, just get yourself a glucose meter, that'll tell you how your body's responding. (Alas, you won't get one funded from the NHS). For the moment you might want to try going for a random figure. Say, a maximum of 80 grams of carbs a day in total. Or if you feel better hitting it harder, to also kick the extra weight quicker and maybe improve your sleeping pattern and fatigue in one go, maybe 50 grams a day? Whatever's convenient for you to start with.

Ditch the obvious and not so obvious carbs, up the fats, keep protein moderate. All carbs up blood sugars, so not just the sweet stuff, but starches too. You can go all out on meat, fish, poultry, eggs, hard cheeses etc. Lots of them! Cut out cereals, pasta's, spuds, bread, rice, corn and other starchy products. Leafy greens are fine, pulses may or may not be, some respond differently to them than others (I can't have them, you might be able to. Your meter'd tell you). Just start slow in re-learning what food means for you. I remember right at the beginning I was afraid to eat anything, everything seemed like poison and I didn't know what was safe and what wasn't. Also because my various dieticians, specialists etc were all giving conflicting information that absolutely clashed with the numbers my meter was giving me. What they said was right, would make me see double digits. (That's
not good). Everything they said I should avoid, gave me beautiful blood sugars, fixed my non-alcoholic fatty liver disease, got me to drop weight (I'm slightly overweight now, used to be morbidly obese, as wide as I was tall), helped my rheumatism, migraines, sneep apnea, fatigue, blurry vision, panic attacks, depression... So I followed my meter. It never steered me wrong.
So it can get better. Honest.
Just pick a number, figure out what works for you, and go from there.
