Sorry about raining on your parade, but we don't even have validation studies to check if it is not snake oil, much less interventional ones that will tell you what to do with the information.

I cannot even say the quoted study is appropriate for evaluating the matter. Reproduction please.

I'm also waiting for a long term followup.
