Actually, fat isn't what makes people fat. Carbohydrates plus genetic susceptibilty makes people fat. The fat content of the American diet has been dropping for a couple of decades, and yet obesity is now at an all time high -- it doesn't take a rocket scientist (hee hee) to figure out that the "eat fat = get fat" correlation just isn't true.
The whole "lowfat/high complex carb" diet push has been a complete fraud -- as I learned the hard way. I kept gaining and gaining, even though I was a serious runner at the time (and that's not supposed to happen.) How I WISH I could undo the damage it did to my body, and get my old physique back! But, at least, by limiting carbs I can prevent it from getting any worse.
and lack of commitment to losing weight after childbirth by women over the years.
Part of this is due to lack of breast feeding. Fat storage during pregnancy is designed to prepare for feeding baby. Without breastfeeding, it may be nearly impossible to take off that weight.

No, there's not. A woman with the right musclo-skeletal structure can be extremely voluptuous, and yet very lean.
The mode of expanded girth is not the issue, it is a fact that has befallen our society over the past few decades. Whether it's a lack of exercise or the alighnment of the planets is not important. People are fatter and thus women are fatter.
My theory of preemptive selection of a slender mate remains a good explanation for the observed selection trend among men and at the very least represents my selection strategy.
No, there's not. A woman with the right musclo-skeletal structure can be extremely voluptuous, and yet very lean.
I still believe that even an extremely voluptuous woman with right musclo-skeletal structure is more susceptible to becoming fat than a genetically thin woman and I would bet dollars to donuts that any data would bare that out.
