Fat Girl Books

So I've been in the mood lately to read books that have the protagonist as "fat" or one could say a "normal" size. Here are a couple of books that have the main character as heftier or chubbier and my scale (ha- pun not intended) of whether they're worth reading or not:
scale= 1-5 with 5 being the highest

Artichoke's Heart- 2 1/2
The Earth, My Butt, and Other Big Round Things- 3
Squashed- 3 1/2
Jemima J- 4 ( though it is an adult book and is a little dirty but it is still a good read)
Angus, Thongs, and Full-Frontal Snogging- 5 (very very funny and the main character is a well endowed, hilarious, narrator)
The Sugar Queen- 3 1/2
My Cup Runneth Over- 4 (I haven't read it but my roommate thinks they're pretty good)
Staying Fat for Sarah Byrnes- 4
The Extraordinary Adventures of Alfred Kropp- 4 1/2
Fairest- 5 (I'm pretty sure that she's slightly bigger)

"Fat girl fiction" has seemed to take off and these are only a few books out there with main characters seen as fat by the general public.
