Keto diet makes your brain use ketones instead of glucose for fuel which results in slower brain aging when you're 40-50.

I wonder is keto on then off better or always on.

On then off might let you get more variety in.

Variety is the spicy of life, and all things in moderation.

It's like asking if on and off cocaine is better than always off... sugar being a sort of cocaine-like thing for the brain.

One thing to note here is that ketosis may be achieved by diets less strict like MAD etc.
