Gary Taubes's 'Uncertainty Principles' Substack newsletter

Advancing

Gary Taubes writes “Uncertainty Principles,” a Substack newsletter he launched after leaving the joint “Unsettled Science” newsletter he had shared with Nina Teicholz. The newsletter has attracted more than 18,000 subscribers, according to the research report, making it Taubes’s primary current publishing outlet.

Recent posts have covered what he describes as bad health journalism, the ongoing debate over LDL cholesterol and saturated fat, and his challenges to the ultra-processed-food framing of nutrition policy. The June 14, 2026 post announced his June 2026 NIH lecture on the history of obesity science, and an essay titled “Diet or Drugs?” lays out his framing of the GLP-1 era.
