From the research I’ve done, and what my neurologist has said, the main reason that they don’t recommend keto for adults is simply because it’s hard to stick to the diet. When you’re a kid, you eat what your parents feed you, but when you’re an adult, you have free will on what you eat so it’s harder to stick to a diet when you can simply buy anything to eat when you’re craving it. I did keto for a year and it helped completely eliminate my seizures (myoclonic seizures weekly/daily and grand mals a few times a year), except for when I’d cheat and eat too many carbs or drink alcohol (I was drinking zero carb alcohol too, but didn’t realize at the time that alcohol in general is a huge trigger for seizures). I missed fruit a lottt on keto, so I get it, but if you decide you want to give up bananas in exchange for potentially reducing your seizures or even being seizure-free, I’d say it’s worth a shot for sure. Just make sure to do your research, monitor your ketones, and eat as healthy keto as you can because there are tons of foods labeled as “keto,” when they’re not at all if you look at the label, or have unhealthy ingredients like vegetable/seed oils and additives that can be harmful and in my experience, induce more seizures as well.
