There is a huge amount of info out there these days. Patients often know more about their own condition than most doctors they will meet.
If you have never fasted before, you need to read up on fasting. If you want to make dietary changes, you read up on lots of dietary stuff. Etc.
If you have a specific diagnosis, you can read up on the latest research into that, plus related stuff. For example, I read stuff about genetics and the gut biome because that helps me put things into context.
You do a thing and something happens. You note it and try to figure out what the process is. Was it random? Was it coincidence? Was it causative? If so, how? You build from there.
