I reversed fatty liver some years ago pre keto by following the suggestions in an Atkins book but I can’t remember which one. It was lecithin, vitamin c and some fibre to get it out of the body because bile dissolves fat but it is reabsorbed in the intestines, which you don’t want if you are clearing fatty liver so the fibre is important. It might have been the Vitanurtirent Solution. Will have a look round and see if I can relocate it.
It was a long time ago and the doctor couldn’t believe I had done it, I was the first patient he had seen who had reversed it.
I got it eating a lot of fruit, I was vegetarian at the time and living in the tropics.
