Persevere. If you suffer from fatty liver it can take 6-8 weeks to release all the liver excess fat stores. This is key to improved insulin sensitivity. I understand that this happens first, before fat burning ketosis of other fat stores. Insulin is a nightmare for promoting fat storage, but it is a really important tool to help keep you free from the toxicity effects of high BGs.
I am now experimenting with more extended fasting (as a T1 ditching insulin will never be an option for me) - 36 hrs x twice a week, as I don't lose weight on keto, OMAD, etc. For consistent BG control I need to be relatively LC or even fully keto.
