I dropped 8 pounds without even trying after I broke up with my longterm BF. I think it's the basic equation that guys eat more than girls and when you're with a guy all the time it's easier to do the same
Or is it that when you're in a relationship you aren't out trying to attract mates, and therefore aren't as health-conscious?
On the flip side, though, I think the argument could me made that there is an incentive to be health-conscious while in a relationship to keep the mate in question.
I'm not sure that people care more when they're in the security of a relationship, because I imagine the relationship is built on more than just superficial factors. You've only got one person to impress (who you know you've already impressed), whereas a single female has multiple suitors to attract.
Interesting theory, but it's never been applicable in my experience. Even knowing that the relationship is built on substance, I think there is still a subconscious motive to maintain a particular appearance. For me, that has been true more so when I'm in relationship as opposed to not. I think I'm in the minority on this issue. And I think this might explain why all of my relationships have failed...
