About this Episode

Dr Herman Pontzer is an internationally recognised researcher in human energetics and evolution. He has conducted pathbreaking studies across a range of settings, including fieldwork with Hadza hunter-gatherers in Northern Tanzania, chimpanzee ecology in the rainforests of Uganda, and metabolic measurements of great apes in zoos and sanctuaries around the globe. He recently released the book, Burn: The Misunderstood Science of Metabolism, a fascinating must-read.

Nathan sat down with Herman and discussed major theories and research relating to metabolism, including the carbohydrate-insulin model of obesity, the role of the hypothalamus in energy expenditure and lesson learned from the Hadza tribe.
