I agree with
@Dazza1984 . I have this too despite being on Metformin for over a year, and am committed to LCHF which I've been doing for a year next month. Fasting BS are known to be the last readings to reduce and after I year I still get quite despondent!
The important thing is not to obsess over your fasting levels, but to focus on your daytime readings, and especially postmeal bs. These are the ones we do have control over by our food choices and our exercise. What did you have with your salmon by the way?
Hang in there and don't get despondent. Good things are happening which a meter can't tell us about!
