Well if you'd watch the movie and read the sources, you'd see that there is not much difference in the amount of calories you burn exercising or sitting at a desk. Consequently you won't loose weight one way or another. Weight seems to be almost exclusively about the calories you ingest. It has little to do with obesity causing less exercise or the other way around. There is not a swathe of pathological things we do that contribute. We eat too much. I also found that surprising. You can exercise without changing your diet, but you won't loose (much) weight. You can sit at a desk and start eating less and loose a lot of weight. |

Exercising without changing your diet is seriously nontrivial for most people, due to compensatory eating - if you burn an extra 400 kCal, you will likely experience commensurate increase in appetite & eat an extra 400 kCal. It takes a lot of vigilance & discipline to avoid that.
IMO that's the 'real' reason diet is a more effective lever for weight loss than exercise. In theory, burning those extra 400 kCal thru exercise is just as effective for creating a caloric deficit as reducing daily consumption by 400 kCal, but in practice it still requires you to eat less than what feels normal/adequate.
