That makes me believe that what they were measuring was not energy expenditure, how can that be the case without breaking the first law of thermodynamics?

- Tade0 2y agoLike I said before: there's a fixed energy budget and you only get to decide what you spend it on, not how much you have. There's less than 10% of wiggle room - the difference between utterly inactive people and those who get at least a little bit of exercise. No real difference between very active people and the former. Similar studies on rats showed that increased activity reduces processes like inflammation, healing of wounds and production of reproductive hormones like estrogen. Essentially our digestive systems are already doing their best. There was an additional study in cooperation with several zoos which showed that other primates work the same. Humans have actually a pretty active metabolism in comparison, as it burns an average of 400kcal more.
