> The answers coming from their data are often surprising: Exercise doesn’t help you burn more energy on average; active hunter-gatherers in Africa don’t expend more energy daily than sedentary office workers in Illinois; pregnant women don’t burn more calories per day than other adults, after adjusting for body mass.

Right, one has to ask the obvious question why do we need yet another study to prove the bloody obvious when we knew decades ago it's calorific intake that's the principal culprit in obesity.
Many (including myself) had come to a similar conclusion about this and other controversial matters such as climate change ages ago, which is that these studies into the obvious/long-resolved facts are conducted to try and convince the skeptics and disbelievers with even more irrefutable solid evidence.
That article puts a very convincing case that that approach is not only a waste of time and effort but it's probably counterproductive—trying to convince those who've entrenched beliefs and or find the truth painful only makes their positions even more entrenched.
