Scott reviews 'The Hungry Brain' by Stephan Guyenet, which explores the neuroscience of eating behavior and obesity. The book presents a 'third model' of obesity, focusing on how the brain regulates body weight through a complex system involving hormones like leptin. It discusses how modern hyperpalatable foods can overwhelm our natural satiety mechanisms and potentially damage the brain's weight regulation system. The review delves into various studies on obesity, including experiments with rats and humans, and explores the genetic factors influencing weight gain. Scott finds the book insightful but notes some ambiguity in reconciling different aspects of eating behavior and weight regulation. Shorter summary

This post discusses a debate about sugar's health effects, centered around Gary Taubes' work. Scott Alexander links to Stephan Guyenet's negative review of Taubes' book, then shares Taubes' counterargument. The debate involves multiple essays: Taubes' initial case against sugar on Cato Unbound, responses from Terence Kealy, Yoni Freedhoff, and Guyenet, and finally Taubes' rebuttal. Scott praises all participants for engaging in a high-level debate that has helped clarify his thinking on the topic. Shorter summary

Scott Alexander reviews Stephan Guyenet's critique of Gary Taubes' anti-sugar book, agreeing with Guyenet's multi-factorial view of obesity and disease causes, and retracting his previous support for Taubes. Longer summary

Scott Alexander reviews Stephan Guyenet's critique of Gary Taubes' new book 'The Case Against Sugar'. Guyenet argues against Taubes' claim that sugar is the principal cause of obesity and various noncommunicable diseases, instead supporting the view that these issues are multi-factorial. The review highlights several key points, including Taubes' selective use of evidence, his dismissal of calorie intake as a factor in obesity, and his one-sided portrayal of historical debates in nutrition science. Scott acknowledges Taubes' past contributions in debunking misconceptions about dietary fat, but now strongly criticizes Taubes' focus on sugar as the primary culprit in health issues. He apologizes for his previous praise of Taubes and no longer recommends him as a source of nutritional advice. Shorter summary
