Clever & sensible.

One potential concern with this would be the possibility of 'upper airway obstruction(s)' (aka, choking). Not necessarily because this position is inherently problematic*, but because it would be a novel position to consume food** in (to presumably most people) and it's a position that most people are likely not used to in the present day, period (i.e., we usually sit up, lie flat, etc., we aren't typically in orientations like this for any real length of time, if at all).

Seems like a clever way to exercise an area that is not easy to exercise in any typical way, but I'd strongly advise caution and awareness of potential aspiration / choking issues if trying it out, at least in initial trials.

* In any anatomical way I can think of off the top of my head

** I would avoid trying to consume liquids in this position, at least initially - aspiration is far easier with thin liquids etc. The author seems to focus on food, in any case.

Could drinking water in this position be a potentially safer alternative?
