Alright, With in the near future I'll write a piece with references.

Point of advice, your body is an adaptive organism. Therefore these studies will reference internal validity and little external validity.

That's something you should consider. Even if you have set up a stud; it will never reflect an individuals reaction to the regime/food/exercise.

Why not? Simply because our bodies reaction to a specific stimulus is not solely based on what is taken/done. It's a whole life endeavor. Be sure to understand that personalized everything will be a thing.

Hope to get on this asap.
