Dr Ken Berry, and Eric Berg on youtube as well as Thomas Delauer will give a lot of good nutritional advice on a ketogenic diet, there's even a vegan ketogenic diet if you're interested.

I hate cooking but have learned to make a pizza crust with almond flour and mozzarella that is to die for. I went off keto in 2020 figured if I was going to die from covid I was going to damn well have chocolate but I'm getting back on it now. I try to eat one meal a day with 20 grams of carbs or less it takes work but I don't go hungry.
