Oh, and obviously exercise helps. Walking and hiking work really well for me. I also enjoy hula hooping to strengthen my middle.

Yeah, obviously. The problem is that I don't want to lose fat all over, just that particular bit! I had it even when I was very thin.

Strength training would be better than aerobic. Hiking/stair climbing, lifting, squats. And make sure you get enough calories, especially fats and protein. You would be re-organizing your body composition rather than burning off all your fat.

Agree with all of those things! and I did make an attempt last year to do them. I have a decent amount of muscle, so it's not that I'm lacking in that department, and I don't need to make up for lack of butt-fat with massive glutes haha, I have quite enough back there. I think diet is defo a major help - since being in spain and having a lot of refined carbs and none of my beloved milk the problem has defo worsened. But even when I'm lifting, slim (but not malnourished) and eating right, I still have this lump under the belly button when I turn side on. It's defo subcutaneous as I can grab it when sitting down (ok, now it's bigger I can grab it standing, too xD).
