I did once have a locum doctor that asked about my control over my type 2 because its fairly obvious I haven't injected with insulin for coming up two years - so I explained that I'm low carbing with occasional fasting and that started her off - she went on for ages about how she'd reversed her type 2 through using the Newcastle Diet and telling me all the things I shouldn't eat. It would have been nice, under other circumstances, to have found a GP who thought low carbing was okay, except that sadly in all other respects she was a nasty piece of work who had so many complaints about her that they didn't have her back after her first week.
I also remember when I was first diagnosed years ago the (then) DN, while giving me leaflets concerning what I should and shouldn't eat and telling me she would always be on the other end of the phone if I needed advice or just reassurance, told me she thought she would become diabetic soon. It didn't instill a great deal of confidence in me.
