Summary
According to investigative science journalist Gary Taubes, m uch of what we “know” about nutrition is built on weak evidence, bad assumptions, and decades of groupthink. In this episode of A Whole New Level , Taubes joins Mike Haney to examine how nutrition science went off the rails—and why he remains convinced the carbohydrate–insulin model still offers the most coherent explanation for obesity. Taubes explains how observational studies became policy, why randomized trials are often ignored, and why questioning the calorie-balance model remains controversial despite mounting contradictions. The conversation is less about winning an argument and more about how science should actually work —especially when public health is at stake.
