C&W: Of course there are exceptions. Genes and environment can be a factor in our behavior.
But a good point was made about burnout. Some women may fight their genes only until they 'hook a man'. My brother dated a beautiful young women for a while; but was quite concerned that the mother was morbidly obese and the girl he dated 'hated to exercise' and didn't own any sneakers. Right now he's dating a woman who just lost 40 lbs from the stress of a divorce AND she smokes. Supposedly she plans on quitting smoking in a couple of months. He will likely break up with her since he's made it clear that he'll never long-term date a smoker and she doesn't seem to be an active person like he is.
I think, realistically, that it's more likely for anyone to fight the urge to eat a donut then it is to fight the urge to kill someone on any given day.
My parents have weight issues. Neither are obese but are overweight. My bro and I have to work hard to not be. Our parents have no interest in proper nutrition and exercise. Big surprise that I was obese for 10 years. My brother, just in the last five years, finally has to watch his diet in his thirties. He's never been more than 20 lbs overweight and he stays pretty active.
I have one girlfriend who's fought 'fat factor' ever since her teens. Got married, had a kid - still stayed slim. Both her parents are fat and she doesn't want to be - she flat-out said that. I know many young women that I've watched grow up since their teens that are fat just like their mothers although they weren't when they were trying to land a man.
Right now I know two young women (17 & 14) that I've known for three years. Both were very slim. The older one is now putting on weight. The parents are both obese. If the 17-year-old doesn't fight it she will look like her mother one day. Her mom was, apparently, very slim at one time. Now I don't know how the woman doesn't tip over from the size of her stomach and breasts (she's very short).
I've three girlfriends that are divorced with kids. All are slim. Would they still be if they were married for almost two decades like me? Maybe...maybe not. One of them had a slim mom, who's only put quite a bit of weight on in the last couple of years because of some medications for an illness. The other two have fat moms. I have one girlfriend that is slim and married and she stays active even in the winter because she doesn't want to put on weight. She's 48. Another is in her 60's and recently widowed and is beautifully slim (always has been). The rest of my girlfriends are married (or widowed) and range from overweight to morbidly obese.
I suppose 'I speak as I see' as Elizabeth Bennett would say (Pride & Prejudice) and am not really interested in the scientific explanation behind genetics or if it could even back up what I observe.
If you stop running and being active and watching what you eat for whatever reason, you'll likely get fat (did you say you were overweight in the past?) and then it's hard to get back into the healthy lifestyle. It becomes a vicious cycle.
Eric Bana is hot. Why? Many reasons. One reason is because he's not fat.
"I use the word 'fat'. I use that word because that's what people are: they're fat. They're not bulky; they're not large, chunky, hefty or plump. And they're not big-boned. Dinosaurs were big-boned. These people are not overweight: this term somehow implies there is some correct weight... There is no correct weight. Heavy is also a misleading term. An aircraft carrier is heavy; it's not fat. Only people are fat, and that's what fat people are! They're fat !" — George Carlin.
