The key is cutting the carbohydrate, so your insulin will drop, which will let your body start metabolising fat. Put enough salt on your food, and you won’t need electrolytes.
NAFLD should resolve fairly quickly after you cut out sugar and alcohol from your diet. Sugar, ethanol, and branched-chain amino acids are all metabolised in the liver, by the same metabolic pathway. This pathway is easily overwhelmed, and when it gets overwhelmed, fat begins to accumulate in the liver. It doesn’t matter whether the FLD is caused by alcohol or not, it’s still FLD.
Give yourself plenty of time on keto before you start thinking it doesn’t work. It’s not a quick fix, it is a new way of life. For one thing, it takes around two months or so to adapt to the new metabolic regime, even though we enter ketosis almost immediately. (And even though fatty liver disease also resolves quickly.)
Keep your carb intake very low, and then eat enough fat and protein to satisfy your hunger. Do not skimp on calories, and do not fear fat. As long as your carb intake is low enough to keep insulin from interfering, you will lose fat. You might even put on some muscle, and your bones might grow stronger, too. So keep calm, and keto on!
