I have read both this book and the Michelle Boasten book and find this one MUCH better. I didn't realize until after I read Michelle's book that Michelle had the mini gastric bypass surgery, which is an old surgery that has been abandoned as being dangerous. Barbara Thompson's book covers everything about the RNY weight loss surgery and what you have to do after the surgery to be successful. It has become my bible. My surgeon recommended this book to me after he had read it. Barbara Thompson brings up important information that I hadn't even thought about. It is very well researched and very personally written. If you get only one book on weight loss surgery, make sure it is this one.
