The Economics of Life: Why Exercising More May Not Help You Lose Weight

03/04/22 • 22 min

Wondering why the "COVID 19" you packed on during the pandemic won't go away no matter how hard you workout? Herman Pontzer, PhD '06, associate professor of evolutionary anthropology and global health at Duke University, says that the problem is in our brains, not our biceps—specifically, the way we understand the relationship between weight and exercise. The author of the bestselling 2021 Book, Burn, Pontzer says that human metabolism evolved over millions of years to defend against weight loss. As a result, the calories we burn every day stay within a fairly narrow range whether we’re gym rats or couch potatoes. This month on Colloquy, the economics of life with evolutionary anthropologist Herman Pontzer.

The Black Agenda

The Black Agenda is a new collection of essays that centers the voices of Black experts—particularly women. Whether the issue is climate change, public health, economic inequality, or education, the contributors to The Black Agenda see social and racial justice as integral—not supplemental—to solutions. Along the way, the book interrogates our assumptions about the ways we live and work together in the United States, as well as our notions of where to look for answers. Join us as we discuss The Black Agenda with editor Anna Gifty Opoku-Agyeman, an author, entrepreneur, researcher, and PhD student at GSAS.

Allison is a leading analyst of national security with special interests in nuclear weapons, Russia, China, and decision-making. As Assistant Secretary of Defense in the first Clinton Administration, Professor Allison received the Defense Department's highest civilian award, the Defense Medal for Distinguished Public Service, for "reshaping relations with Russia, Ukraine, Belarus, and Kazakhstan to reduce the former Soviet nuclear arsenal." He received his PhD from GSAS in 1968.
