I wanted to read this book to get a better understanding of the connection between un recognized food intolerances or sensitivities and health/disease. As the title indicates, the focus is primarily on weight loss, but the idea is the same. While I have yet to cut out ALL of the seven foods, I have cut out gluten and dairy and have greatly reduced the rest. It was an easy read and she spells out how to reintroduce the potential trigger foods to determine if you have a reaction.
