I stopped reading as soon as I saw:

> They began by recruiting 32 men and women who did not exercise.

This is not worth reporting - certainly not in the matter-of-fact manner that they did. It is far far more likely there is nothing worth seeing here.

I wish I had the resources on hand to explain why I believe this. It relates to p-hacking and finding results that just fade away with more in-depth investigations.

32 doesn’t mean the criteria for something that should be reported to the general public. Investigated further? Sure.
