I'm looking for anything that has some reasoning/science behind it.
In essence, the recommendation is to eat a low fat diet with the goal of losing weight. In addition, avoid alcohol use, as you should with any liver issue.
There's really no magic to most dieting needs (there are some that require medical intervention, but your health professional should have gone over them). Rather it's more an equation: [calories in] - [calories used] < 0 leads to weight loss.
