A review of the carbohydrate insulin model of obesity and the related proposal that low carbohydrate diets are superior to traditional low fat diets. I begin with a discussion of the theory behind the carbohydrate insulin model, and then assess its plausibility using relevant evidence from rodent studies, dietary studies, ahd controlled feeding experiments. I argue that the scientific evidence does not support the alleged benefits of low carb diets for weight loss in otherwise healthy adults. Recommended pre-listening is Episode 151: Diet and Nutrition, and Episode 152: Obesity, Diabetes, and Hypertension.

An interview with Ariel Zeleznikow-Johnston, author of the book 'The Future Loves You: How and Why We Should Abolish Death'. We begin by discussing how best to define death, focusing on the idea of death as the permanent disruption of psychological identity, and how such identity is constituted by our personality, desires, and memories. We then consider the science of brain preservation, including the recently-developed technique of Aldehyde-Stabilized Cryopreservation, and how it could be used to indefinitely preserve the brain structure that encodes or personal identity. Ariel argues that such a preserved brain could potentially be used to construct a digital simulation of our brains, essentially allowing us to survive the biological death of our bodies. We conclude by considering some potential challenges of implementign such a technology, and whether it would achieve widespread social acceptance.

A review of the science between the metabolic syndrome, including discussion of obesity, diabetes, hypertension, and hyperlipidemia. We discuss the pathophysiology of how enlargement of adipocytes disrupts metabolic signalling pathways and leads to buildup of lipid intermediates. We then consider how these effects impair health, examining the causes of insulin resistance, atherosclerosis, and dysregulation of blood pressure. We conclude by looking at how such symptoms lead to pathology and increased mortality in overweight and obese individuals. Recommended prelistening is Episode 151: Diet and Nutrition, and Episode 18: Biochemistry Basics.
