Just been thinking.. I did make one change I have been doing 16:8 fasting most of the time.
No breakfast except coffee, something to eat as late morning as I can go, lunch, dinner and nothing after 8pm.
I've not been hungry generally. Metformin could well be having effect on appetite. I don't even think about putting a large portion on my plate anymore. It's always a sensible small size. And rarely have the desire to carbs binge either which is a relief.
