Since this thread is on the tangent train now:
The key factor here is that we have a choice....we can choose to just go with our biological impulses and not think about consequences, or we can choose to behave differently. If people were merely biologically driven and nothing else, society would be quite a different place IMO.
But that's not a choice. Let's use a smoker as an example: They start smoking even knowing the health risks. Why? Let's say peer pressure. We are prone to cave in to peer pressure because our genes tell us this is a good thing. Now what if someone explains to that smoker exactly what happens when they smoke? Either the smoker quits -- because he now fully grasps the weight of what is happening to him, his priorities have changed and he gets determination from the aforementioned -- or he doesn't -- because he likes the fix he gets and withdrawal is too unpleasant. That's not a choice: that's one set of stimuli outweighing another set of stimuli.
Psychologists are mostly there to clarify and weight a decision more favourably. They are just another set of stimuli.
The term you're looking for is 'pleasantly plump' and I too am fond of females matching this description. Though I don't find skinny pretty at all, and find pleasantly plump gorgeous. I also don't think it automatically makes them smart, or that being skinny automatically makes them dumb.
Not automatically, but it does skew the chances. And yes, I meant "pleasantly plump", not "fat". I'm not a feeder.
But I have no intention of losing weight

Slightly overweight people, on average, outlive their skinnier compadres.

I don't know really how to explain it. I just don't find it attractive. Obviously everyone is different - personally I prefer guys that are tubby, bordering on fat. However that's not to say guys who spend time in the gym aren't attractive. It's just not what I'm looking for personally.
There's been a study that indicates that different body types give a general indication of personality and background. When you say you're attracted to overweight guys, what you're saying is you're attracted to the personality and background that comes with it.
