This was a really powerful book. I felt that Robin poured herself into this novel, because you can't write a book about such a personal issue without having some back story. Maybe I am wrong but that is the impression I got.Cat is a like-able character she is funny and unlike many other fat book main characters she does not really look down on herself. Because I am scientifically minded as well I enjoyed how she made changing her life into an experiment. All of the nutrition advice, while sometimes being too much, was informative, and interesting. This book really inspired me to get up and eat healthier.Besides the nutrition aspect, the love story was really cute, while sometimes being obvious, i really loved Matt, and her other friends were so wonderful. I would love to be friends with any of these characters.I enjoyed this book, it made me look at my eating choices through a good plot, and a cute love story. One of my favorite books I read in 2009.
