I think getting any clear results in nutrition is essentially impossible because you can't conduct the studies necessary to get rid of all the confounding factors. Consequently it's probably a bad idea to follow an extreme diet. Of course that doesn't mean that keto (or other dietary interventions) can't be beneficial for certain illnesses like cancer. I'd be interested to hear about studies.

Our modern standard diet is very extreme by default.

I'd guess practically any other diet would be better.

I guess it depends on your culture what the "standard" diet is. I don't think my diet is particularly extreme.

The one that has white flour/rice and sugar as the main staples. You know what I mean; it's cross-cultural now, like tobacco smoking.

[adrianN]

The diets in the "Blue Zones" feature those as staples as well. I somehow don't think that they're terribly unhealthy. Grains have been staples for millennia by now.

The bread we eat now and the bread we ate 150 years ago are very different breads.

The modern stuff is refined flour and sugar.
