Cat is obsessed with hating Matt Mckinney. All she wants is to beat him in the science fair. Then she gets the picture and her science fair project takes on a life of it's own. She's eating the way the hominids did and kicking technology out of her life. As she changes her diet and walks everywhere, the pounds start melting off and the male population takes notice.
I really enjoyed reading this. Cat was incredibly funny and I loved the relationship she had with Amanda, Jordan and her parents. The relationship she developed with her brother was just amazing to watch and reminded me of how my relationships with my sister developed.
I also really appreciated that the book was't preachy about the diet and technology give up. Yes Cat clearly felt this was working very well for her but it didn't feel like it was pushing it b/c it was more about Cat's internal change. I was also happy that the author stressed that even though Matt could be considered the catalyst for the change, really Cat did everything for herself.
I did have to giggle a little bit about what Cat would sometimes consider a "technology worthy emergency". They were very much teenage girl type emergencies. Also Amanda was an amazing friend and everyone should be so lucky to have a friend like that in their life
