High protein intake shouldn't be a recommended keto diet, because the body will use gluconeogenesis to process protein into glucose, so you'll never be on ketoses, and therefor suffer from all side effects mentioned by you. It should be a diet high on fats.
Totally agree that in current times food is an addiction. Since when do we need to eat 3 meals a day? At least 90 percent of modern humans history, we used hunting and gathering to survive. Only in the last 10 percent we have agriculture, and much much later, refrigerators, supermarkets and convenience stores. If we needed this much food our species wouldn't last a week before agriculture. Spoiler alert: we lasted 300,000 years.
I would like to see more researches on ketosis diet. Seen by medicine as something that occurs when in starvation, I see it as the natural state of the human body. I eat once a day and I don't feel like I'm starving. And when I eat I don't feast.
I consider sugar to be no different from cocaine (not that I ever tried), but we crave for it the same way people who consume that drug or any other, crave for. Sugar is everywhere, and it's our main source of energy, being that our body feels terrible when its levels are low, but as soon as you eat it feels wonderful. The same goes with cocaine.
