Funny that this gets upvoted so high and a more reasonable article that was posted in the same day (https://news.ycombinator.com/item?id=10931349) did not.

I've done ketosis, high carb, and moderate carb, and the fact is that while ketosis can work for some, it can be damaging to others. I tried keto for a while and it raised my fasting blood glucose levels to pre-diabetic levels. As soon as I went back to a moderate carb intake, my blood glucose was back to near-ideal. Obviously you should take further tests (HbA1C) to be absolutely sure if you're at risk, but it's not all smiles and rainbows for keto, you really need to make sure your body can actually adapt properly to the changes that are going on in your body as a result of the diet that promotes keto.

More people find articles discussing what is possible more interesting than a summary article. Xavi was interested in ketosis, read about the subject, saw that runners like Tim Olsen had done well on a paleo-type diet and wondered about long-distance running in ketosis, followed through on the experiment, and wrote it up. To me that is the ideal thing to post here.

I've had a similar experience. I researched that and found that in those conditions having a fasting glucose that is higher than the "normal" range is not a problem, just an adaptation. I had HbA1C done several times and the results came back perfect.
