As I've posted before on other Threads, nothing in the body happens in isolation, and things like weight, blood pressure, diabetes, cardiovascular problems, and cholesterol levels are all interconnected
As mentioned in the earlier replies, if you change your diet to low carb and also cut out stuff like burgers, pizzas, other fried food, and processed & junk food in general then your pre diabetes, weight, and general health will improve.
This would mean no more, or very greatly reduced, bread, pasta, spuds, rice, cakes, biscuits, sweets, booze, and more veg, salads, olive oil, fish, especially oily fish, and all the rest of the healthy stuff we hear about
Making the changes can be daunting and difficult at first, but as you do it, so you do more, and it just becomes a new & different way of living
Your taste will change, and you will no longer want to have things that are very sweet, fatty, or salty
Have a look through old Threads, especially Newcomers, Food & Carbs, and Weight Loss. There is a lot of information and your questions will almost certainly have been asked before
And if you have any more questions, or want encouragement & reassurance, ask again
