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
