Cookbook to loose weight?

[Fess]

Hi,
I'd like to loose some weight, not much, specially around my butt, this is where all the "stuff" goes.
I bought this book mistakenly, I don't know if it's helpful for me or it's better for those who want to lower their cholesterol?
Can anyone suggest me a good book ? My friend says I should have a book with low fat cooking but I believe that I should eat less carbs, too.
Thank you!
