Sounds like you are doing the right thing, and doing really well too.
High initial IR (insulin resistance/fatty liver disease) , can sometimes mean it takes a bit of time to get the system working to a degree where fat loss can occur. One of the early episodes of The Fasting Method podcast was about this topic.
Do you try to avoid omega-6 oils, including olive oil?
(Some research has indicated that omega-6 plays a large role in causing IR.)
Do you drink black coffee?
Multiple reports (although only anecdotal/survey) have suggested that coffee perhaps helps against various liver issues, including IR. (Adding artificial sweeteners and especially plant based ‘milk’, would be detrimental though.)
