I had moderate NFLD and managed to get rid of it completely by just eliminating fried food, most dairy, and sugary snacks for about 6 months, I also almost never eat red meat. It's not so much about being overweight, but what you're eating.
But it isnt pushed hard because it is difficult to steer the ship of humanity. Like how doctors will say "lose some weight" but they arent really expecting miracles on it as they know the battle that is.
I eat around a pound of beef a day, a gallon of yogurt a week, and almost everything (eg oatmeal) is made with copious amounts of butter.
I think unless you know something specific about your genetics, just eat plain natural foods people have been eating for millennia and you will be perfectly fine. Basically, buy plain meat, vegetables, grains, and dairy and prepare them yourself. Don’t eat preservatives, corn syrups, or novel vegetable oils like canola. Maybe they’re fine but there’s no reason to risk it. Also do your best to make sure what you eat followed the same rule; eg my beef was grass fed and finished and was not fed skittles in a feedlot. Diet affects animal meat as well, just as it does us.
If someone wants to try limiting meat consumption as an "n=1" experiment to see how it affects their body composition and other biomarkers then go ahead. Just don't expect a major impact from that one factor.
