How do you tell them nicely...

To be completely honest, I would just tell them that you're not as attracted to them as you once were. Let them decide whether they want to make the change or break up. If somebody changed their personality -- or their priorities regarding things other than weight -- over the course of the relationship, and you were no longer attracted to them because of that, you'd have no problem breaking up with them. If you got into a relationship with someone who was really nice and over the course of the relationship they turned into a big bitch to the point where you were no longer attracted to them, you'd break up with them. If sexual attraction is important to you in a relationship, why should you treat that differently?
