I've been doing the carnivore diet for more than a year now. Outstanding health benefits and I'm never giving it up. I didn't have fatty liver disease, but a lot of people who do report that the carnivore diet fixes that fairly quickly.

It's also a lot easier and more enjoyable than counting calories (which I did for a while as well, with decent results, but damn, it's is not fun).

The carnivore diet is not popular with mainstream media and medicine (which is a good sign, in my opinion), but if you search on youtube for fatty liver and carnivore, you'll find lots of information.
