Guest Bio

Herman Pontzer, PhD

Dr. Pontzer is an associate professor at the Department of Anthropology, Hunter College & City University of New York. He is an evolutionary biologist with a PhD in Biological Anthropology from Harvard University. He has published seminal work in the area of energetics, including viewing human energy expenditure via a model of constrained total energy expenditure. He s truly a world-class leader in this field and has been repeatedly recognized internationally for his research.

In This Episode We Discuss:

  • Constrained vs. Additive model of total energy expenditure
  • The physical activity paradox: Do highly active populations actually burn more calories?
  • Why NEAT, movement efficiency and other metabolic adaptations can’t fully explain the paradox
  • Why did we evolve this way?
  • Why are human capable of expending so much energy in acute time frames?
