Gary Taubes on respect for clinical experience as evidence: recommends

Gary Taubes says the spread of low-carbohydrate and ketogenic practice was driven not by resolved theory but by physicians and patients seeing results — what he calls “conversion experiences.” In a 2026 LowCarbUSA interview, he said the movement grew from “a dozen physicians” using low-carb diets 25 years ago to “tens of thousands” today.

His stated reasoning: he argues that this clinical diffusion is itself meaningful evidence — that practitioners adopting and sticking with an approach because they watch it work in patients should count in the scientific ledger, alongside (and sometimes ahead of) formal trials. He presents this as his explanation for why low-carb practice outran the published literature.

Criticism worth noting: mainstream nutrition researchers generally respond that uncontrolled clinical experience cannot distinguish the intervention’s effect from placebo, selection bias, and confounding — the standard reason observational and anecdotal evidence is treated as hypothesis-generating rather than decisive.
