Grade 3 Fatty Liver. Suggest diet?

I have been diagnosed with a Grade 3 Fatty Liver in Nov having CAP 303 and KPA 11. I have reduced my weight from 125 to 120. In mid December I got another Fibroscan done. This time CAP is 338 and KPA 6.5. Since then I have reduced another 4.5 Kg of weight. But sometimes I feel slight pain or uneasiness in the right side of the ribs area. Current prescribed medications are Bilypsa and thiotres. Can someone tell what exactly is happening and is there any need for change in medication? Also can I take a Liver Detox capsule consisting of Milk Thistle along with current medication? Can someone suggest diet? I am pure vegetarian and mostly getting protein from Double Toned milk, paneer, curd, butter milk, besan, legumes, soya chunks. Also, using mustard oil mostly and sometimes desi ghee. Max 20 ml per day. Also, I have kidney stones in both kidneys 3.1 mm and 2.4 mm.
