if you want to write something with the intention of venting your frustration, i understand that. and maybe it's not fair that you're not getting a lot of interest, but there is probably something you can do about that.
i don't know what your health situation is, but health matters. why wouldn't a woman care about that? for me, health is kind of a big deal. the idea of you joking about being a bulimic to lose weight isn't terribly funny--and sort of tells me that you might have your priorities messed up, because health isn't just a scale number. health is a reflection of a holistic condition.
here's something to think about. do you believe that you deserve to be with a healthy woman? emotionally? spiritually? physically?
the fact is, most of those women have options, and what they're looking for healthy. confident, and secure. someone who is grateful, happy, and values himself as evidenced by the effort/care taken to be a good steward with the most important resource you'll ever have -- your body.
i'm sure there are women who will accept less, but you'll need to change your expectations. i apologize if this sounds harsh, as it's not my intention to offend, but to be helpful. : )
finally, i would ask a couple female friends to review your profile. someone who knows you well and can possibly help you refine it to reflect an accurate, yet positive reflection. i have seen a handful of guy's profiles, and some of them read as depressed or downtrodden. even verging on pitiable.
i think intention was to sound modest, but it reads as "woe is me". and women aren't attracted to a negative, insecure, or anything that sounds like a "feel sorry for me" tone. this may not be your problem at all, but it could be a real problem if it is.
also, stop worrying about the numbers. big deal if you haven't had a lot of success. how many women are you really looking for in the end?
