2928: Being Fat and Fit Is Objectively Better Than Being Skinny and Unfit — Here's the Data

Sal, Adam, and Justin break down the research showing that being overweight and fit yields similar or better longevity outcomes than being normal weight and unfit — a counterintuitive data set that challenges the cultural obsession with leanness. They explore why frailty is one of the highest risk categories in medicine, how muscle serves as metabolic currency and glucose storage, and whether looking better actually correlates with happiness. The episode also covers industry news including Procter and Gamble's acquisition of Thorne, the history of tobacco companies applying addiction science to processed food, Myspace's no-algorithm relaunch, and an Anthropic study where AI detected something planted inside its neural network.
