@Ultramum I think you have your plan spot on.
After stopping cheese, cream and nuts I've lost weight.
I got my bgs and fbg towing the line 90% of the time.
In fact just booked my hba1c for next tuesday (result end of that week or monday).
Have you found reducing or aliminating carbs to help a great deal? I had to reduce protein too, in the end as my bgs just crept up as my day progressed.
I reduced my insulin but the background part of my mixed insulin was missed more than the fast acting part with lc. Hence I had to increase it and start again.
Currently I'm still using insulin 3 times a day on lower units but metformin is on hold again as just over a tummy bug.
My plan was to walk then jog and swim my diabetes into no insulin and just metformin for a hormone problem but my pelvis and lower back had other ideas. Humf!
I walk to my local shops when I can but heavily rely on painkillers and sensible diet to keep my bgs low.
The lower and steady they are for me helps with weight lose.
