Detoxes. Seed oils. Cortisol making you fat. Artificial sweeteners causing weight gain. Insulin as the root of obesity. Hormones as the master switch for fat loss.
These ideas keep spreading — even among smart, educated people who should know better. In this episode, Dr. Layne Norton explains why.
This is not just another myth-busting list. It’s a breakdown of the psychology, incentives, and media dynamics that make fitness misinformation so sticky. Layne covers why the human brain was not built for science, why anecdotes beat statistics, why fear sells better than nuance, how algorithms reward certainty and outrage, and why intelligence does not protect you from bias.
You’ll also get a practical toolkit for evaluating claims: what questions to ask, which red flags matter, how the hierarchy of evidence actually works, and why the “big rocks” of health still outperform the latest viral villain.
If you’ve ever wondered why bad fitness ideas travel faster than good evidence, this episode is the map.
