because they were much less fat than us, had almost none of the diseases we have that are all really metabolic dysfunction/diabetes at their root, and the general price and availability of food has only been getting better…
What does that have to do with ketosis? You can eat a lot of carbs and not be fat...
> had almost none of the diseases we have that are all really metabolic dysfunction/diabetes at their root
True. Unless you were rich. Even heard of gout? But yeah probably somewhat accurate for the whole population. But again, not much to do with ketosis.
I mean is there any evidence even today that someone whose diet is primarily (~80%) grain and other plant products with a lot of carbohydrates can enter ketosis even when practicing "intermittent fasting" while consuming ~2000-3000 calories per day (e.g. the estimate for standard Roman soldier daily rations is 3,000-4,000)? Seems impossible...
not really. its extremely well established science. you dont seem to have much experience with this topic. ketosis saved my life in 2019 and ever since then ive been learning as much as i can about ketosis and its medical applications
Why? Of course Northern European had different diets (e.g. lard instead of olive oil etc.) but on the Mediterranean cost diets weren't that similar.
> you can enter ketosis every day on a diet of carbohydrates by eating one or two times a day
So being on the brink of starvation all the time? Does not seem sustainable.
> all of this could have applied to most people until relatively recently
Highly unlikely. What makes you think that was the case?
