ABSTRACT
Leah is very interested in the contribution of specic foods to the growing obesity problem in America. She has read many diet books, and they seem to contradict one another. She wants to get a better perspective, based on true scientic data and not on propaganda. For her senior thesis project, she decided to research the physiological mechanisms that lead to obesity. As she got into her library research, she found that nutrition was only one part of the obesity problem.
