For a book that is tackling a fairly complicated subject, this was a nice, easy read. Normally, I don't like reading one-person examples (they just can't be spread out to the larger public) but this book made it work by peppering the beginning, middle, and end between the more laborious and intensive scientific studies. It gave each of those studies a more personal feel while giving the personal stories more credence.
I'm not sure on the last chapter with the author's experience. She talks about losing her extra weight but it's SUCH an extreme diet. And, again, it's that one-person-one-outcome that I don't love.
Four stars
