No, that's not how that works.

The people saying that fasting made their symptoms worse in that paper are the patients, not the medical professionals.

Your individual experience does not override theirs.

That doesn't mean it was just coincidence and that it didn't work for you, of course. The average experience doesn't override your personal experience either. But it does very strongly indicate it not only wouldn't work for everyone with those conditions, it would make a lot of them worse.
Wow. This is very interesting. I have had some residual smell/taste issues since I had Covid in October 2021. Was attempting to use autophogy as a tool to clean up these loose ends, so I have fasted a bit since end of December. All of a sudden about two/three weeks ago, my sense of smell went bonkers, and I think it may have been around the time I did a three day fast after having recently done a two day and some 20:4 IF. I haven't been able to figure out what triggered this, but now I have to wonder if it is related. This is going to take some sorting and processing.
