Is it okay to eat fatty foods once in a while even if im diagnosed with fatty liver?

Fatty liver.: Those with a fatty liver should generally limit fat intake, limit alcohol intake and lose weight (if there's weight to lose) via proper diet and regular exercise. That being said, it would be OK to treat yourself to a fatty meal every once in a while, meaning once a week or two. Realize that all meals will have some fat in them, so it's not like you're completely avoiding fat otherwise.
