I've been at this UC gig for many years and can't say i remember everything I've tried. I've most certainly tried the most common described diets here and given them ample time to work. I've seen many examples of diet doesn't work for everyone, and it isn't a lack of trying, dedication, or willpower that's the culprit in it not working for us lol (a common claim). UC is extremely individual, and there's no universal treatment for everyone. Everything is hit or miss
