A body made in code

[DerVVulfman]

So what you're considering is an enhanced version of the hunger/thirst/sleep system. Insofar as foods, you could go and make different foods give different results (meat vs fruits vs starches..... vs beer). And you would likely need a stamina/drain system so you can get fatigued. You can have different stats that can make the player weak besides that, such as blood loss.

And here I was thinking you were revisiting the old 80's movie, Weird Science.
