I'm so glad that there is a dialogue about women's body sizes in magazines.  On one spot about the photo some guy said that (and I'm paraphrasing) "Women don't want to see that in a magazine.  They want to see what they aspire to be."  Seriously, Mr. Man? 

Women come in all sizes and shapes and can still be HEALTHY.  That's the key word.  HEALTHY -- their physical health as well as their emotional and mental health. 

There are naturally thin women, yes, but the majority of models that you see in magazines (except for sports/bikini magazines) have underweight BMIs.  Are they healthy?  Is that what we should aspire to be?
