Clock Icon $15
Age Icon All Ages


Join author Herman Pontzer, Ph.D., and Stephen Ross, Ph.D., director of the Lester E. Fisher Center for the Study & Conservation of Apes, to explore the metabolisms of humans and apes.

Pontzer’s new book, “BURN: New Research Blows the Lid Off How We Really Burn Calories, Stay Healthy, and Lose Weight,” took off on Amazon as a fitness bestseller within hours of its release. During this one-hour virtual chat, Pontzer and Ross will talk about metabolism, water, how we train, and how our knowledge about great apes can help us understand ourselves.


Herman Pontzer, Ph.D., Author

Pontzer studies the physiology and evolution of humans and apes to understand how ecology, lifestyle, and diet affect metabolism and health. His work has spanned across species and populations, from lab studies in the U.S. to working with hunter-gatherers and subsistence farmers in Africa and South America to research with apes and other primates in zoos and the wild. His book, “Burn: New Research Blows the Lid Off How We Really Burn Calories, Lose Weight, and Stay Healthy,” came out this spring.
