Why We Get Fat: Adiposity 101 and the Alternative Hypothesis of Obesity: In this lecture, Gary Taubes will explain his theory on why obesity is not caused—as conventional wisdom has it—by eating too much and exercising too little, but rather by the effect of the carbohydrates we consume on the hormones and enzymes that regulate our fat tissue. Rochester-native Gary Taubes is the author of the bestselling Good Calories, Bad Calories: Fats, Carbs, and the Controversial Science of Diet and Health and Why We Get Fat: And What to Do About It and is an award-winning science writer and a correspondent for Science magazine.
