I’d say that it goes further than just wanting.
I want to lose weight, it’s bad for my health and makes it harder to find clothes that fit. However, it doesn’t feel wrong to be fat. The other body related stuff feel very wrong though, like it’s a deformity that should have never been there (if you take the view that gender dysphoria is an intersex condition then there is an argument to be made for it actually being a deformity).
I can’t find a source for it now, but I remember reading about people who had limb deformities who would feel like they had normal limbs. That is the closest description I have found to what I feel every day.
I would like to emphasise that I am not speaking for anyone else but myself.
