Wow, that's bizarre - where did you hear about that? Awesome if it works, sure isn't something I'd think of on my own.
The whole goal of Keto is to up your intake of healthy fats, of which Coconut oil is a prime example.
Once you are in ketosis, a serving of healthy fats will keep your body running for hours, because your body is now using fat as the fuel instead of sugars and carbs.
Living the fall of an empire sucks!
