Exploring new ideas is a great way to learn and stay motivated.
Some 20 years ago i tried combatting eczema outbreaks on my arm by going vegetarian. Didn't change a thing except make me fart more often and absolutely disgusting smell. I kept doing it anyway because you know, animals cute, veggies healthy.
I gave all that up around 2010, then went keto 3 years later. That was where i first noticed an absolute boost in my nutrition. I hardly had any farts anymore. The eczema had meanwhile moved from occasional outbreaks on my arm to occasional outbreaks on my calves.
Then around 2 years ago i started experimenting with carnivore and i went a bit more hardcore into it a while ago for the first time and it felt ok. I still think there's benefits to be had from certain plants and some are probably actually healthy but i feel better than ever before. I lost some additional weight and gained quite some muscle. Haven't seen any eczema anywhere for 2 years.
All i'm saying is: keep exporing and diving into things that you find interesting and may change your perspective. If it's all hogwash you can always go back to doing what you did before.
