I'm not sure I understand the method.

Is it correct that the study looked at the effect of a single (large) dose of ketones, rather than ongoing consumption?

As I understand it, dosage was 0.395g per kilo of body weight (so about 27g for 70kg subject), and that was it - with measurements of brain activity before and after.

No indication of duration of effect?

I Googled and have found a product on Amazon, which is asking about 30 USD for that dose, which would make daily 900 USD a month (!)

You can make your own ketones by downing some MCT oil. Cheap AF. Just have to be somewhat fasted.

Been looking into this.

Looks like blood concentrations peak about 30 mins after ingestion, then back to normal after about 120 minutes.

No info about how this relates to effects or duration of effects on cognition.
