So you really like the girl, but because she is poor and not as in shape as you are you dont want her? Seeing the state of the American (im guessing you are) economy, i dont think you can blame someone for being poor. And a bit overweight, eh, that can be fixed, especially if she has a history of being active im sure it wont be that hard to get her to join you at the gym or something. So, I would say those two are pretty superficial reasons to reject a girl you admit you really like.
The Asian thing though, if thats your preferred type and you know its going to bother you in non-Asian girls, why even try and date a non-Asian girl?
*edit* about the poor thing, i just noticed this topic:
53% of those w/ bachelor degrees age 25-and-under in the US are jobless/underemployed. So yeah, you can pretty much count on a girl to be poor these days, even if she is college educated.
