No matter from what angle I try to make sense of that statement, I only arrive at it being bullshit.
At best, they have a standard grade sensor that, in a narrow band of perfect circumstances, makes a statistical guess that arrives at barely workable accuracy (article notes 80-90%) for a reading of something that is almoste entirely unrelated to your blood glucose level. Even if it was reasonably related, it would still not tell you anything at all about what you've eaten.
Water moves in and out of cells via osmosis in an attempt to equalize solute concentration on both sides of the membrane. This is a passive process not controlled by insulin. You can place a cell in distilled water and watch it grow or a saline solution and watch it shrink.
