"What is it like in ketoland? Well, for one thing I only need 4 hours of sleep. Asthma, which has plagued me all my life, is now nonexistent. Wrinkles have melted from my face, like wax from a burning candle. I have boundless energy. The best comparison I can come up with is the transformation Jeff Goldblum underwent in David Cronenberg’s (1986) The Fly. Come to think of it, he was probably also on a LCHF diet. Hopefully, I won’t experience his complete transformation."
I think if you're worry about carbs from cauliflower as he does you don't understand this way of eating well enough, and I for sure don't spoon-feed myself coconut oil. I did at the very beginning, when I was both low-carb and low-fat for a couple of weeks, since I didn't really understand what I was doing, and had cut out linoleic acid as my primary fat but not replaced it with anything. Boy, was that spoon-full heavenly at the time!
What was really interesting about that experiment was that my body didn't crave linoleic acid in any way. It was only the healthier fats that I would fantasize about.
And I never noticed any reduction in sleep requirements, but then people are variable.
