If ketosis is your aim, then get ketostrips and see for yourself. (But I would be surprised if the possible couple grams carbohydrates here is sufficient.)
As far as intermittent fasting and etc, this isn’t enough calories (UNLESS oil suspension softgels).
It depends on your definition of ‘fast’.
People with epilepsy doing the strict keto diet to control seizures, have to watch toothpaste and even lotions because they have carbohydrates that can kick them out of ketosis.
