> FWIW, I hear there could be issues with (too much) iron especially for men.

Too much iron can cause serious systemic issues, especially for the liver, and yes, men tend to have worse symptoms for the simple reason that one of the treatments for high iron is bloodletting. Unlike women, men don't have a natural built in mechanism to do so regularly.

Note that you have to eat a lot of fat. It's not "high protein", it's "high fat, medium to low protein".

> At any rate, do be aware that human biology is quite diverse and diets that work for one may not work for others.

Only these type of diets may work for the diseases that I mentioned. Like it only works for some types of epilepsy.

It's actually the reverse. "some people" is every person that is overweight (50% of USA). "cancer" are studies where it includes other things, like fast food etc. Haven't researched arteriosclerosis, but we'd have to see studies being done on healthy patients with strict keto/carnivore and not dirty diet.

No, there aren't. And no, you haven't ready any reputable studies where people did clean keto/carnivore.

All your studies are people just talking about their diet, eating meat & stuff. And that "meat & stuff" never works on treating any diseases either.

Feel free to link anything from "everything I've ever read about high red meat consumption" and we'll see if it's true keto/carnivore/ketovore.
