I have observed the dawn phenomenon since diagnosis where my BG will be high upon waking (100-110), but before dinner I will be in the 70's or low 80's. It's been getting better, and my morning numbers are in the 90's now. I am on 500mg Metformin ER and while it does not seem to help lower my A1C much, it does help with the dawn phenomenon.

I do IF and usually only eat from 6pm-9pm, usually one or two meals in that time. On workout days or the day after I may eat lunch depending on what my body is telling me in the way of hunger. As I lose weight my NAFLD is improving, and AST and ALT readings are normal again. Any change in diet is taxing on your liver, I think the OP needs to give it time and continue to monitor.
