Carl Franklin and Richard Morris welcome Marty Kendall, a civil engineer fascinated with nutrition, to discuss his work dissecting our relationship between food, nutrition, metabolism, and weight loss. A hallmark of Marty's work is describing the best approach for different metabolic states and body types. This is a fascinating discussion that explains a lot of our eating behavior in the last 50 years. Carl talks about his experiments with macadamia nuts, the results of which support the science.
