So I was looking at making an Unchained monk and going through the Meditation Master feats. Looking at the Unchained ki power Ki Metabolism, It reduces food, drink and sleep requirements to 1/4 normal. There's also the Body Control feat out of the Meditation Mastery feat list which reduces the above by 1/2.
... quite simply, how do the two interact? do they? or do they overlap?
