EP 159: Gary Taubes on Why We Get Fat

What makes us fat? It’s a contentious debate in the world of health science. Is obesity caused by energy imbalance — consuming too many calories — as has long been conventional thought? Or is obesity caused by the effects of carbohydrates on insulin? My guest on today’s program attended an invite-only global gathering of obesity experts. The resulting paper in Nature Metabolism, co-authored with fifteen other researchers and published this fall, compares the two competing hypotheses side-by-side, as equals. Which, my guest writes, “has never before happened in the century-plus history of meaningful research on the cause of obesity.” Gary Taubes is an award-winning investigative science and health journalist. His latest book is Rethinking Diabetes: What Science Reveals About Diet, Insulin, and Successful Treatments. With the journalist Nina Teicholz, he writes the Substack newsletter Unsettled Science.
