This book is a plagiarized copy of a book my wife Judith Wurtman and her co author Nina Frusztajer wrote. The original Serotonin Power Diet was published by Rodale in 2006. It contains clinical studies carried out by Dr Wurtman at MIT and Harvard University and the experiences of both authors running a weight loss program.
The premise of the book is based on my own research at MIT. The so called Dr Hanson has stolen the material and published it under his own name. Do not buy it.
