Pre-diabetes was rejected as a diagnosis by the World Health Organization (although it is used by the US and UK) - the correct term for the condition is impaired glucose tolerance. Approximately 2% of people with "pre-diabetes" go on to develop diabetes per year. You heard that right - TWO PERCENT. Most diabetics actually skip the pre-diabetic phase.
There are currently no treatments for pre-diabetes besides intentional weight loss. (Hmm, that's convenient, right?) There has yet to be evidence that losing weight prevents progression from pre-diabetes to T2DM beyond a year. Interestingly, drug companies are trying to persuade the medical world to start treating patients earlier and earlier. They are using the term “pre-diabetes” to sell their drugs (including Wegovy, a weight-loss drug). Surgeons are using it to sell weight loss surgery. Everyone’s a winner, right? Not patients. Especially fat patients.

Also - I love what Dr. Asher Larmie @fatdoctorUK has to say about T2DM and insulin resistance, so here's one of their threads I pulled from Twitter:
1️⃣ You can't prevent insulin resistance. It's coded in your DNA. It may be impacted by your environment. Studies have shown it has nothing to do with your BMI.
2️⃣ The term "pre-diabetes" is a PR stunt. The correct term is impaired glucose tolerance (or impaired fasting glucose) which is sometimes referred to as intermittent hyperglycemia. It does not predict T2DM. It is best ignored and tested for every 3-5yrs.
3️⃣ there is no evidence that losing weight prevents diabetes. That's because you can't reverse insulin resistance. You can possibly postpone it by 2yrs? Furthermore there is evidence that those who are fat at the time of diagnosis fair much better than those who are thin.
4️⃣ Weight loss does not reverse diabetes in the VAST majority of people. Those that do reverse it are usually thinner with recent onset T2DM and a low A1c. Only a tiny minority can sustain that over 2yrs. Weight loss does not improve A1c levels beyond 2 yrs either.
5️⃣ Weight loss in T2DM does not improve macrovascular or microvascular health outcomes beyond 2 years. In fact, weight loss in diabetics is associated with increased mortality and morbidity (although it is not clear why). Weight cycling is known to impacts A1c levels.
6️⃣ Weight GAIN does NOT increase the risk of cardiovascular OR all causes mortality in diabetics. In fact, one might even go so far as to say that it's better to be fat and diabetic than to be thin and diabetic.
Dr. Larmie cites 18 peer reviewed journal articles (most from the last decade) that are included in their webinar on the subject, linked below.
