["Hi! I've been losing weight recently and it's helped with my anxiety.", 'I bet you feel great too.', "I definitely do. It's amazing."]
That is awesome. Congrats!
I actually lost weight.  I didn't intend to at first, just went through a rough patch, but then realized I was losing and kept at it in a better way.  And a lot of other issues eventually went away becuase of it.
