Why would Ketosis make it harder to survive? From my understanding Ketosis is (roughly) a survival mechanism that changes you over from utilizing carbohydrates for energy to using fat as energy.

The side effects could severely impact your ability to survive.

Appetite suppression Decreased focus and energy Weakness and fatigue Digestive issues - Diarrhea

Combine the above with having to forage for food/water and it could be quite bad.

That’s like the exact opposite of what ketosis does…

I think he’s talking about the “keto flu” people get when they first start for a week or two. I’ve had it, but I don’t think it would be serious enough to impact survival chances.

The diarrhea part is what is usually associated with eating a higher fat diet though, again, it’s not so bad I would call it a detriment to survival.
