Fat confusion

Yesterday I read this really confusing article about the need to lose the pregnancy weight within one year after child birth or there would be health issues. I read the article in a news/tabloid type paper (again, confusing) and they referred to Diabetic Care magazine, and for the life of me, I can't find ANY references to such an article. Or an existence of such a research.
(Turns out that the paper referred to the wrong magazine and has since then removed the article from their site. I did find another article, which I will link to below, that talks about gaining weight post partum, not keeping the weight gained).

And this is seriously pissing me off.

Not only are people hounded about their weight on a regular basis, now women who just went through massive amounts of pain, nausea, sleep pwning, and sleep deprivation have to work out to lose weight, because apparently new mothers have to lose the weight or it will be bad.

Didn't we already have the whole discussion about stress dieting and  the good things about keeping a level weight? Didn't researchers debunk the whole FAT IS NOTHING BUT BAD myths? Didn't we already find that ALL BODIES ARE BEAUTIFUL?

Leave people alone already.

"Fat" is a noun, representing a part of our bodies, in most cases crucial for muscles and brain matter to function properly.

"Fat" is an adjective, representing a person who is bigger than the norm dictates bodies to be.

"Fat" does NOT mean lazy, ugly, stupid, or disgusting.

New mothers have enough on their schedules, with all the diapers and feedings and sleep deprivation and other things new parents do, in addition to healing from child birth. They do NOT need some doctors/advertisers/fashion police shaming them into adding exercise to their lives.

This article talks about health risks associated with gaining weight post-partum and same risk factors if women don't lose their "excess weight" post partum. As far as I can tell, it's a relatively small study, conducted at one research center. I will never have kids, so this doesn't apply to me, but I'm curious to see the developement of these findings.
