If you ignore pre-diabetes it will turn into diabetes. I did, and then 5 years down the line I was diagnosed with T2 during pregnancy, they said I would have had it for a couple of years even though I did not think I had any symptoms (turns out I did, but not symptoms you would think of such as frequent urination etc so I never put two and two together).
I used to binge eat carbs and it was such a difficult cycle because for diabetes the spikes in blood sugar can give you crazy hunger, I would try to be "good" but could only hold out so long and then eat my way through any carbs I could get hold of.
As I was ashamed of my binges they would only occur in secret. So a tip would be that while you are trying to stop binges, don't be alone. Don't start a very restrictive low calorie diet, gradually reduce. Fibre is your friend when it comes to diabetes, and of course protein and fat to replace some carbs. Each diabetic has different triggering carbs, personally I can't tolerate more than one slice of wholemeal bread for breakfast, and brown rice is worse for me than wholewheat pasta. If you can buy/borrow a blood glucose monitor to see which carbs are most triggering for you then it may help you psychologically to know that while potatoes are out, moderate amounts of bread is OK.
Losing weight will help with stopping pre diabetes turn into diabetes, but better blood sugar control, and exercise should be a more immediate concern. I wish I had not ignored pre diabetes, I was already more susceptible due to family with it, and now I am 34 facing decades of being careful with diet, worrying about premature death, at greater risk of heart disease, kidney disease, nerve damage, eye damage, risk of ketoacidosis, risk of T2 turning into T1....I wish I had known how awful diabetes was and shocked myself into taking more care to avoid it.
In short: don't be an idiot about it like I was
