And there are some like me who are diagnosed as T2 but maintain low prediabetic levels long term through low carbing.
I usually eat max 50g carbs a day but it could be under 20g depending on what I eat or how often. This seems to be what my body - and glucose levels - are happy with. I don't actually count now, just check new foods... and I reduced my initial HbA1c from 61-62 on diagnosis to 47 at my next review a couple of months later
without counting/measuring anything and before I found our forum and discovered I really ought to use a meter - I just cut out all the obvious high sugar foods to start with and then all high carb stuff when I realised that it wasn't simply sugar that was the issue. I found it easier to impose a blanket ban then eventually did some fine tuning after I got my meter, and I'd always eaten full/normal fats all my life, so only had to make a few small adjustments to the amount I needed to replace the carbs.

And PS I'm another who doesn't count this as limiting, it's my preferred diet rather than a self imposed restriction...
