As a pediatrician, I strongly believe in the power of prevention. And this book is all about preventing and treating long term medical issues, like diabetes, heart disease, and joint problems by aggressively treating the underlying chronic disease, obesity. The authors make a compelling argument, backed up by evidence, that the only way to lose significant weight and keep it off is to have professional help. I strongly recommend this book for anyone who has been struggling with weight issues, chasing diets to lose a few pounds only to gain them right back again.
