Terrible reporting here. This has nothing to do with sitting, it has to do with inactivity. You can have an active lifestyle and still sit all day. Later it states
> blood glucose levels fell back to normal levels after a meal far more quickly on the days when the volunteers stood than when they sat.
So what? If you don't have a medical condition related to elevated blood glucose having meal related glucose levels take longer to return to baseline shouldn't cause problems. I'm not aware of any research stating otherwise. Please correct me if I'm wrong.
There are problems due to sitting though, such as
> a sharp reduction in the activity of an enzyme called lipoprotein lipase
and as they mentioned standing burns far more calories (the article said 50/h) which is a good thing.
I'm all for standing but it'd be nice for reporters to get their facts straight.
