@thomasfuchs You do need a balance though, without the hard science available yet. I'm an engineer, and the woo-woo stuff drives me nuts. So much BS out there
My story. Long covid made me bed bound for months. I could not stand more than a minute or two, and they looked at giving me oxygen. I was living and working from bed.
Over time, I found that a careful diet avoiding carbs and sugar controlled it. If I cheated the fatigue would return like clock work, along with heat palpitations. I absolutely hated it but it worked.
Metformin has been shown to help reduce long covid risk by controlling insulin, so it is likely I hacked my way there. Who knows yet. The science can't happen fast enough.
I then got covid again and it cleared out my long covid. I like to think my diet helped but who knows.
I hate the randomness of this disease.
