Episode notes

Olive oil contains a compound that disrupts the mechanism of developing obesity, acting as a double-edged sword depending on the individual. In a study, individuals who switched from sunflower oil to olive oil were more likely to develop obesity. This finding is statistically significant and contrasts with the dominant narrative, highlighting the complexity and nuances of nutrition research.

On this week's podcast, Brad Marshall, evolutionary biologist, talks with Paul about how signaling to our body that winter is coming is not advantageous for humans and why humans may want to stop consuming olive oil. They do a deep dive into the human metabolism, what European diets are truly like, and touch on other kinds of oils & fats as well.
