The Criticism of Keto-CTA—and What the Data Actually Show – TFP #021 | Greg Mushen

In this episode of The Feldman Protocol, Greg Mushen, a longtime technology and product leader turned independent health researcher, makes the case that disciplined thinking from Silicon Valley can meaningfully inform nutrition and metabolic health. The discussion also directly engages with debates raised by the Keto-CTA study, using it as a case example to examine data transparency, scientific criticism, and decision-making under uncertainty—alongside metabolic testing innovation, walking versus high-intensity exercise, protein prioritization, and Greg’s own body recomposition—through a skeptical, analytical lens.
