Taubes on Why We Get Fat

EconTalk Episode with Gary Taubes
Hosted by Russ Roberts

Gary Taubes, author of Why We Get Fat, talks with EconTalk host Russ Roberts about why we get fat and the nature of evidence in a complex system. The current mainstream view is that we get fat because we eat too much and don't exercise enough. Taubes challenges this seemingly uncontroversial argument with a number of empirical observations, arguing instead that excessive carbohydrate consumption causes obesity. In this conversation he explains how your body reacts to carbohydrates and explains why the mainstream argument of "calories in/calories out" is inadequate for explaining obesity. He also discusses the history of the idea of carbohydrates' importance tracing it back to German and Austrian nutritionists whose work was ignored after WWII. Roberts ties the discussion to other emergent, complex phenomena such as the economy. The conversation closes with a discussion of the risks of confirmation bias and cherry-picking data to suit one's pet hypotheses.

Taubes on Fat, Sugar and Scientific Discovery

EconTalk Episode with Gary Taubes
Hosted by Russ Roberts

Gary Taubes, author of Good Calories, Bad Calories, talks to EconTalk host Russ Roberts about what we know about the relationship between diet and disease. Taubes argues that for decades, doctors, the medical establishment, and government agencies encouraged Americans to reduce fat in their diet and increase carbohydrates in order to reduce heart disease. Taubes argues that the evidence for the connection between fat in the diet and heart disease was weak yet the consensus in favor of low-fat diets remained strong. Casual evidence (such as low heart disease rates among populations with little fat in their diet) ignores the possibilities that other factors such as low sugar consumption may explain the relationship. Underlying the conversation is a theme that causation can be difficult to establish in complex systems such as the human body and the economy.
