Sorry LentilWeaver, I'm not sure if this post was aimed at me.
I've been similar to you, in that as I am Asian with a strong family history of Diabetes,
had a BMI of 27.5 and I was just in the range of prediabetic so I was eligible and decided against.
I did have food noise but have never really been a big eater. Because of my family history I'd become insulin resistant.
As I say, I didn't want the jabs. I read about Michael Mosley reversing his prediabetes and the research at Newcastle University and to cut a long story short...tried the recommended ways of eating, lost the weight, reversed the prediabetes and haven't had any bother since. It only took 6 weeks for it to turn everything round for me. The first 5ish days were rough but after that it was easy...since then I just count my macros and as long as I don't regularly go over 130/140 g of carbs it's fine. If you don't have food noise or sugar addiction, I'd say it's totally doable without the jabs.
Relatives recently diagnoses in the diabetic or prediabetic range have been offered Metformin or Emflagalozin (think I've spelled that wrong, it's a medicine that makes you wee out sugar) as a starting point despite being over BMI 30. They've also had loads of nasty side effects...none of them have changed their diet much.
I think if you can do it with diet alone, it's a much better approach, though I appreciate not everyone can. Touch wood, I may be the only one of my family to avoid Diabetes and medication for it altogether according to the HCPs I've seen recently. That's a big deal considering how many of them are on Insulin or have needed amputations/have sight loss etc.
I am pretty evangelical about the Fast800/Newcastle Diet
