*Content warning up top: This episode discusses sensitive themes like diet culture, caloric intake, the psychological & physical effects of food restriction and includes many listeners’ personal experience with the term “obesity." It may be triggering for those with a history of or sensitivity to disordered eating. We also discuss the Body Mass Index, still used by medical professionals, but acknowledged by many sociologists to be rooted in structural oppression.*

Let’s explore our human machinery. And talk about Brazilian butt lifts. Professor of Evolutionary Anthropology and metabolism researcher Dr. Herman Pontzer gives us the data on mitochondrial backstories, muscle mass and hormones, our expanding brains, the flaws of the Body Mass Index, humans’ relationships with nutrition, why crash dieting can change your metabolism, perspectives on sticky medical terms, isotope magic, how much exercise hunter gatherers get, carnivore diets, scales, and what to do if you're grappling with sadness.

In part 2 of our interview with Ky and Lee, we discuss how anti-trans groups campaigned to influence medical organizations like WPATH and drew in vulnerable people along the way.

We start with a story designed to hit so many of our pressure points all at once: police have been using pseudoscience machine learning to render 3D avatars of suspects from DNA samples, sometimes from decades ago, and then running these 3D avatars through facial recognition. Then, ending with less horrific and more absurd, we get into an interview between Peter Thiel and John Gray where we learn a surprising fact about Thiel. ••• Cops Used DNA to Predict a Suspect’s Face—and Tried to Run Facial Recognition on It https://www.wired.com/story/parabon-nanolabs-dna-face-models-police-facial-recognition/ ••• John Gray and Peter Thiel: Life in a postmodern world https://www.newstatesman.com/ideas/2024/01/john-gray-peter-thiel-discussion-post-modern-world Subscribe to hear more analysis and commentary in our premium episodes every week! https://www.patreon.com/thismachinekills Hosted by Jathan Sadowski (www.twitter.com/jathansadowski) and Edward Ongweso Jr. (www.twitter.com/bigblackjacobin).
