"Losing Weight Without Losing Your Mind" - a detailed examination of why overweight people are no different from slender folks, psychologically. The root causes of the problem are entirely non-psychological...they are gene/environment relationships. The solution is to eat a diet consistent with human natural history and your personal genetic requirements. Also integrates the importance of fire and food processing in human history, and the significance of each with respect to weight. The core argument is calorie density, but the other issues - cooking, processing, genetics, are all important. Finally, everyone understands that superhuman self-discipline over portion control to lose weight is just a prescription for "losing your mind", as portion control is completely inconsistent with biological design. Always very well-received, a major self-esteem booster for overweight people.
