***Update***
Well, as expected, my specialist was overwhelmed at the result! He took me off Metformin straight away and said check A1c/lipids in 4 months. He gave a sharp intake of breath when I mentioned LCHF but quite rightly agreed he could not knock the results.
He was slightly concerned that my HDL and LDL cholesterol levels were respectively too low and too high but they are literally borderline so recommended eating more oily fish:
Serum HDL 1.1 mmol/L
Calc LDL 3.0 mmol/L
So it is well and truly a maintain for me from here on in! Hopefully continuing LCHF/IF will maintain my A1c levels without the need for Metformin - I'll let you know in 4 months!
Thank you all for your wonderful support - keep up the great work and good luck with all your personal journeys.
