My friend went through IIN's health coaching training program and said it changed her life and that this book was a big part of it. I was impressed when she sent me this link to download it for free and have been really enjoying it. It's cool that instead of just telling you what to do, they basically train you to listen to your body, mind and heart to learn what it really wants to eat and what other types of "primary food" like social, spiritual and physical activities that will make you really "full". I also really like their focus on the way you eat being as important as what you eat. I definitely have found that eating with more awareness has made me feel like I digest it better, know more when I'm actually full, and enjoy it better too.
