Body asymmetry

Hello there! I like my body and all but I am just concerned. My upper body is super fit all the time, no belly fat (and almost no boobs btw) but my lower body is really bigger. Like there would be a big difference if I measured my waist and then butt.

Now I am sick and I lost 6 pounds in a week. My lower body is still the same while by collarbones are starting to be visible. I don't like it at all. I know it's normal that boobs go first when it comes to weight loss, but this seems a little bit weird to me.

Do you have any advices? I am a bit concerned.
