Lots of interesting thoughts here.
Off hand I can't recall how food or lack thereof affects sleep but what subjectively happens when one is starving or cuts out carbs is that sleep seems to suffer. I know one way to get subjectively more pleasurable sleep is to have a lot of carbs close to bedtime.
When one artificially increases testosterone it usually increases sleep. But sure, for some the other way around. I know the more gear I take the more I sleep. Look at pro bodybuilders, they look like they are about to fall asleep all the time.
I'm not an alpha in any way but I'm wound tight with high anxiety. My doc said to me as a kid that I'm the type who in pre-modern times would guard the tribe from external threats lol. My sleep requirements have always been extremely high, abnormal even.
Arnold is the type who claimed he hardly slept, said he didn't want to miss out on everything life had to offer, he would sleep when he was dead. But I would sort of counter this, especially someone who took this as advice, that if everything we know says you suffer cognitively from too little sleep then the quality of those life experiences might suffer also.
At 41 I am in best shape of my life, thanks to intermittent fasting, or you can say by eating 2 meals a day.
My energy levels gone through the roof.
The reason is simple, digestion and insulin fluctuations diminish one's life energy.
When you eat less often, you produce more GH and you have much more stable blood sugar levels, and you spend less energy on digestion.
I also believe you can not force being a short sleeper.
Imagine a major general, high functioning, very competitive and demanding.
Have immense responsibility, very sharp with so much things to consider.
I believe you need to withstand pressure, lack of sleep to able to be a major general.
If you are not competitive, demanding, a kind of burning soul, you sleep like a baby.
I am also far from alpha, I enjoy good sleep, too agreeable and I am not burning with majestic goals.
Arnold was burning with incredible goals, I guess when you have potential and vision, it is like a self sustaining nuclear reaction.
But without tools you can have all the will power and ambition, but it won't cut it.
