I echo the others. Get another beta. Personally, I'm getting tired of reading about thin heroines. Second I crack open a book, and read about the heroine not being hungry, or complaining about her thinness, I want to break her twiggy little arm! IN THREE PLACES!
The girl in my WIP is chunky, and battles her weight constantly. The boy in my WIP loves her big boobs and ass.
Sometimes it feels to me like the only heroines I'm seeing are ones who have "luscious curves" and big boobs and asses. I'm barely a size 2, barely a B-cup, and not particularly curvy at all, and was made to feel less of a woman all my life because of it. I actually gained a bunch of weight at one point in the hopes that it would give me curves; it didn't. It just gave me a big stomach, and because I'm small-boned my features all but disappeared. So I figured slim was the best look for me, and started being careful about what I ate, and lost 40 lbs. I'm still not curvy, and I'm still envious of women who can wear push-up bras and actually have something to push up, or who have hips and therefore fill out the hip parts of dresses and skirts, but at least it works for my body type.
I don't understand why we have to be prejudiced about the size of heroine at all, be they big or small. It's not okay to get pissy about a woman because she's "fat." It's also not okay to get pissy because she's "thin." Women come in all different shapes and sizes, so our heroines should too, and we shouldn't try to make each other feel ashamed or embarrassed for being any particular size and/or shape, you know?
There is absolutely a market for heroines with a little meat on their bones! I see tons of them. Yes, it depends on just how big she is; is she thirty pounds overweight, or a hundred and fifty? The latter may be more specialized, because I believe that would make it a BBW book (Big Beautiful Woman), and those are generally a smaller market. But just being heavy, I don't think is a problem at all, and I think your friend is being kind of weird about it.*
*I will say, though, how much time, if any, does your heroine spend obsessing about her weight, or worrying about it, or talking about it really positively, or whatever? It might be--probably isn't, but might be--that it isn't her size that bothers your friend as much as the amount of words the book spends on it, do you know what I mean? A heroine who constantly talks about diets and her weight and how much she hates her body isn't generally really appealing to me; neither is a character who totally advocates being overweight (or anorexic) and spends all of her time thinking hateful things about women who aren't. You know?
There's nothing wrong with making her physically imperfect--that's a great thing. There's nothing wrong with having her accept herself and be healthy--that's also a great thing. There's nothing wrong with her acknowledging her flaws--great as well. And there's nothing wrong with having her want to do something about those flaws, although it's not necessary IMO. But when it turns into obsession, or pettiness about other women, I don't like it.
I guess for me a heroine who spends so much time thinking about any aspect of her physical appearance can seem kind of shallow to me. That's not to say it always does, just that it
can.
But your friend's reaction really sounds to me like prejudice, so I wouldn't worry about it, and I certainly wouldn't change my book because of it. Your character is overweight because she is. if she wasn't, she'd be a different character; every aspect of a person makes up who they are, you know? So unless the heroine's weight takes up most of the story (see above, lol) I'd ignore her comments and find someone who accepts that not everyone is perfect.
