Losing weight should be simple: eat less, exercise more. But according to author and health journalist Julia Belluz, it's complicated. Listen as Belluz talks with EconTalk's Russ Roberts about her new book, Food Intelligence. Belluz argues that a calorie is pretty much a calorie whether it's carbs or fat. Keeping calories under control is often harder than it sounds. The message isn't blame; it's agency with compassion: understand your body's feedback loops, redesign the choices around you, and choose a sustainable way to enjoy food. At the end of the conversation, Belluz makes the case for government intervention of various kinds to help us make what she sees as better food choices; Roberts pushes back.

Steven Pinker on Common Knowledge
Why are Super Bowl ads so good for launching certain kinds of new products? Why do we all drive on the same side of the road? And why, despite laughing and crying together, do we often misread what others think? According to bestselling author and Harvard psychologist Steven Pinker, it all comes down to common knowledge, or the phenomenon that happens when everyone knows that everyone else knows something. Hear Pinker and EconTalk's Russ Roberts explore the necessary conditions for that knowledge, and how it can be both vital and dangerous to societies, depending on how it's used. They discuss, among other things, game-theory puzzles, how laughter spreads, how totalitarian regimes exploit uncertainty about who knows what (even when they don't), and why we often don't say explicitly what we really mean to say.

How Did America Build the Arsenal of Democracy? (with Brian Potter)
American manufacturing of aircraft during WWII dwarfed that of its enemies. By the end of the war, an American assembly line was producing a B-24 bomber in less than an hour. But that success was far from inevitable. Structural engineer and writer Brian Potter speaks with EconTalk's Russ Roberts about the logistical challenges of ramping up production from virtually nothing, and the incredible balance of precision and improvisation required to respond to constantly changing aircraft designs. They also discuss the limits of industrial mobilization, why early preparation proved so critical, the role of women in the production process, and what lessons this experience can offer today's debates about supply chains and defense readiness.

How Teams Succeed (with Colin Fisher)
What makes some groups thrive while others crash and burn? According to organizational-behavior scholar Colin Fisher, the real villains are rarely individuals, but dysfunctional teams and organizations. Listen as he and EconTalk's Russ Roberts discuss the reasons for the free-rider problem and the importance of meaningful, well-defined tasks to incentivize synergy. They speak about why most team-building exercises are usually a waste of time, and why the best way to build trust is simply to do the work. Finally, they explore the role of great leaders from Steve Jobs to Bill Belichick in elevating groups into teams, and offer lessons from history's great projects for increasing productivity.

Humans Are Overrated (with Christine Webb)
Are humans the most intelligent species, or just the most arrogant? NYU primatologist Christine Webb, author of The Arrogant Ape, believes that human exceptionalism is a myth that does more harm than good. Listen as she speaks with EconTalk's Russ Roberts about how research has skewed our understanding of animals' capabilities, the surprising inner lives of animals, and how a shift from dominance toward connection with the larger living world can help humanity.
