Catrin, I have nothing to add about the thyroid, etc., but could you try maybe cutting out the beer or wine? I know that's what I do if I have a couple of intransigent pounds. I know it kind of sucks, as you and I are not huge drinkers, but basically it's empty calories and beer, especially, has a lot of carbs.
And, you can't exercise 24 hours a day. Your diet looks pretty good to me, so tweaking small things might work instead of trying to do more.
