I'm a dude and I have only read a few of the top posts in here which talked about how demoralizing these mags can be to women with SAD. I just had to say this...
Those magazines absolutely disgust me and when I see a woman reading one it honestly COMPLETELY turns me off and makes me feel pretty disgusted and disinterested and, most significantly, untrusting of that woman, her honesty and her general morals. I see those things everywhere in the hospital I work at and... whaddya know... the place is filled with disgustingly insecure, rude, pathetically shallow, no sense of humor-having women (not ALL, but very close to it, unfortunately).
I just wanted to say that if you are disgusted with those magazines you should feel good about yourself because I guarantee you that 99% of guys are disgusted with women who read those types of mags. Feel free to get your girly thrills on by reading them if you enjoy them... I don't COMPLETELY judge a woman because shes reading one (guys like sports, girls like gossip, I'm not judging)... but don't ever let them effect your self confidence other than to boost it by realizing you are above all the BS shallow disgusting crap they put in there.
As for fashion mags, I am pretty disgusted with the ideal emaciated female body type they portray as well, but at least they aren't full of disgusting gossip/sex columns and page after page of brutal judgments on how people look or dressed.... freaking disgusting.
