Gary Taubes on resolving the obesity-theory debate experimentally: recommends

Gary Taubes says the carbohydrate–insulin model of obesity and the energy-balance model should be treated as genuinely competing hypotheses and tested by rigorous trials. He frames the disagreement not as settled science but as an open scientific question that deserves decisive experiments.

His stated reasoning: he argues that the history of nutrition science shows institutional momentum locking in under-tested theories, so the only honest path is to fund experiments capable of genuinely distinguishing between the competing models. The framing was echoed in the 2024 Nature Metabolism consensus paper “On the pathogenesis of obesity: causal models and missing pieces of the puzzle,” which he co-authored with 15 other obesity researchers — a rare instance of the field jointly acknowledging what it does not know.

Criticism worth noting: some experts consider experiments such as Kevin Hall’s NuSI-funded metabolic-ward study to have already falsified the carbohydrate–insulin hypothesis; per Wikipedia’s entry on the model, “proponents disagree” and “available evidence does not support the existence of a long-term advantage in weight loss for low-carbohydrate diets.”
