I take stuff for my adrenals too already and, like you, when I started Iodine supplementing I lost about 2-3 lbs but nothing since then.
I do better gluten free in terms of clearing brain fog but it doesn't seem to do much in terms of weight loss. But, a friend with Hashi's went gluten free and lost weight like mad.
Just so frustrating because I am so active, etc. Am just going to try Wommie's way of eating (along with some of that moss, lol, if I can get some).
