I have read the posts on underactive thyroid with interest - I have had to take thyroxine for the last 6 years and my weight gradually crept up, and I have found it very difficult to keep below 11st.
In America they apparently believe that just supplementing with thyroxine l is not enough and you need iodine supplements too.
I asked at the doctors' and the chemists and got a sort of 'you don't want to go there' brush-off with no real explanation.
I have however started using iodised salt for cooking and putting on food, and since Christmas have lost half a stone, and had to go out last week to buy a new pair of (smaller) jeans.
Of course I have no way of knowing whether my weight loss is due to the iodised salt, or the fact that I retired at Christmas and now spend most of my time gardening , walking and playing tennis
Anyone know anything about the iodine connection?
