Aaron E. Carroll:
But standing is not exercise. Many health groups recommend that people at work take frequent walking breaks. Replacing sitting with standing does not fulfill that recommendation and may even mislead people into thinking they’re doing enough activity.
Standing desks are “overrated” in the same way that any other health advice is: it’s not a panacea so stop treating it like one. That said, reading this article, I can’t help but think the advice is: change positions often. As a long time standing desk user I think you are far more likely to change positions often when standing than when sitting. Say, 100% more likely, as that’s quotable.
