I really like this blog post from Romancing the Blog.
Let's be honest here: I know I'm fat; I know I'm overweight and I should weigh less for health reasons; I know that I'm slowly working on trying to get the weight off. Trust me, I'd love to weigh 115 lbs, like I did in high school--I was a freaking size 4! (I still have my favorite pair of jeans from then, in the obscure hope that I will one day fit into them. =) But the reality is that there are many, many women in America like me, who are relegated to the plus-size shopping stores: let's call us the Lane Bryant crowd.
Now there's nothing wrong with Lane Bryant. A lot of the clothes are trendy and young enough for me to wear (I'm still in my 20s, after all), and many of them are very pretty. Some of my favorite shirts have come from there, and I've even gotten compliments on them. Yet despite the fact that there's a raging obesity epidemic in America, plus-size women often get short shrift in romance novels, along with just about every other type of novel published. Yeah, there's the sub-genre of "fat girl getting thin and finding a man", but that doesn't really make for an empowering book.
So here's my challenge for the rest of you. Write a short story or a novel, and put a plus-size woman in it. Make her feel beautiful, like she really is; all women have breasts and hips and curves, and every single one of us knows how to use them. Don't be prejudiced against your character, just because she doesn't weigh the same as a feather. Attempt to actually depict the current reality of many American women...you may be surprised with what you come up with!
