The Proof

Nutrition and lifestyle science, interviewed at length.

Newsletter Health Weekly Updated Aug 2026

About

The Proof is Simon Hill's long-form interview show turned newsletter, going deep on nutrition and lifestyle science with researchers, physicians, and scientists instead of chasing quick takes. Protein requirements, plant-based diets, sleep, longevity: whatever the topic, it stays anchored to what the actual studies show.

The format rewards patience. Episodes and the notes that accompany them run long, working through nuance and caveats rather than flattening a complicated literature into a headline. Readers tired of oversimplified health advice tend to be the ones who stick around.
