Best diet for stroke recovery?

My dad just came home after suffering his second stroke... All they told me was that he has to be on a strict diet—no fatty foods, no high salt intake—but honestly, I have zero clue what that actually looks like in practice. I’ve been scrolling through stuff online saying to avoid greasy meats, processed deli meats, salt, and dairy, but now I'm stuck. I have no idea what to actually put on his plate.

Breakfast is the biggest headache because how am I supposed to feed someone who's spent their whole life eating heavy, greasy meat and won't settle for anything less? (And here's the kicker: he deals with mental health issues too, so my long-winded lectures about how fat ruins your arteries go completely in one ear and out the other). So, does anyone know if there's a way to make breakfast healthy but still filling enough? Especially since he's also diabetic... (I mean, how am I supposed to convince a 240-pound guy to just eat a tiny bowl of oatmeal, an apple, and some low-fat yogurt?) Help me out here... 🙂

Also, totally separate from the food thing, why do they need to keep checking his potassium levels after a stroke? Is that part of the stroke recovery or is it related to something else? And what else should I be watching out for while he's recovering?

The doctor gave me this super blunt, clinical explanation of everything, and I was honestly in such total shock that I couldn't even bring myself to ask follow-up questions. I'd really appreciate any info you guys can share about this—anything at all. I don't have anyone else to turn to for advice, and I don't know a single person who's gone through a stroke before. Thanks...

Cut the salt out of your diet entirely, and make sure you're loading up on fish, fruits, and vegetables. You also need to stop frying your food altogether.
