I don't think there is a difference between the genders on this issue. People will prefer their partner not being overweight, but it doesn't mean we won't date someone that is overweight. As we get older our physical standards drops to stay aline with realistic expectations. Extreme obesity however, isn't ever going to be attractive to either gender.

Unfortunately in my experience yes. I can tell the difference in attention I receive from men with just a fluctuation of 20-30 pounds... I get much more attention when I am thinner :(
