Hashimoto's here. The problem with all of these diets is that its not known if they actually do anything and the source is usually a mommy blogger who's making money from selling supplements.

I tried to talk to a few doctors and the only one(yes, one) who didn't dismiss the whole thing mentioned that there's nothing conclusive about any of these diets besides some well known diseases such as celiac and gluten. He told me to try it out if I wanted to and see how i feel but don't go to drastic measures because you could be depriving your body of nutrients it needs. I guess that's why the recommendation is always a varied diet; nobody knows what the body needs exactly so eating everything in moderation is likely to give your body anything it could need. Not really scientific though, is it?

So my question is, how do you know what fad diet actually works? Searching for peer reviewed published work on anything nutrition related is a futile endeavor.
