What's a "healthy-weight" model look like?

As a quick follow up to yesterday's post about The September Issue and the world of fashion and body-consciousness...I was chatting with my good friend and editor at Glamour magazine, Margarita Bertsos (who has a great weekly blog with Glamour fyi). She mentioned that a photo of a real-life woman with a real-life weight on page 194 of the current September issue caused a quite stir. Lizzi Miller, a 20-year old plus-size model, is pictured in the buck with just underwear...and a small roll at her belly. And she's gorgeous. The related story discussed feeling comfortable in your own skin (as I briefly mentioned in yesterday's post).
It garnered so much attention that editor-in-chief Cindi Leive blogged about it herself....and had a response of nearly 1,000 comments!
I think it's fantastic that such an prominent women's fashion magazine like Glamour is making efforts to reach out to their readership in different ways. They're depicting normal, real women and we as readers relate that much more (hence the 1,000 blog comments!). But it also shows a hopeful shift in body-image and what's "ideal" and what's "normal." Your body's healthy weight is normal! Celebrate your curves people, we all have them...even models! What are your thoughts on the photo?
