I think I'm in this camp. My priorities were firstly stop the nasty symptoms I'd had for ten years - neuropathy, oedema, kidney problems, wounds not healing etc. etc.
To achieve that I had to reduce my BG.
To reduce my BG I went (and have stayed at) ~20g carbs/day. Took four months. I was somewhere over 120kg when I started, and was still about 110kg when my A1c was back at 36 (down from 50).
I've lost a further >15kg since, still losing, and my BG has stayed around 36-38 in the intervening two and a half years. Weight loss (fat loss, strictly speaking) is to my mind a by product, not the cause, of my BG reduction.
