We weren't suggesting not trying them. I tried quite a few different diets because there was no guarantee that it wouldn't help. I do object to claims that "The <whatever> diet is the answer to everyone's health problems!!". We all differ too much, and what works for one will be bad for someone else.
Some diets are relatively cheap, easy, and safe to try, so there's not much reason to not try them. Others are expensive, especially the proprietary ones, and others have some risk of harm, so I would suggest doing proper research into them before taking that risk.
You're absolutely right! I misunderstood, my bad. My eyes have been acting up and brainfog has been worse than usual this last week so I have trouble with reading and comprehension 🤯
