The Hadza study has some interesting implications, but a lot of the reporting on it has massively blown it out of proportion. They walk 4-7 miles per day while burning a total of an average of 2500 calories. That's fewer calories than expected, but not actually by all that much. Two hours of walking per day sounds like a lot compared to an office worker who does not engage in any sort of physical activity, but it's quite small compared to what people who work physically demanding jobs or do any meaningful amount of cardio training get.
- Tade0 2y agoThey don't just walk. Their whole lives are physically demanding as they do everything by hand. The men hunt, the women forage. Everyone crafts their tools. Also it's not just this study. Research on this actually started in the 1980s when the double labelled water method became practical - unfortunately it's still massively expensive. All in all there's a much larger body of research indicating that exercise is not effective at controlling weight. The Hadza study at least gives some clues and indicates that there's something we're missing and this mechanistic approach to metabolism where you can just coax it into burning more is a model that doesn't reflect reality.
