in this case deviant behavior means alcohol consumption or eating disorders.

Imaging if you were able to drink a whole 26oz bottle of vodka without issue, and then you then had half of your body removed. attempting to drink the same amount would be like drinking double what you had been, since you have half the body left to absorb and buffer the effects of alcohol. Could be a recipe for death. Same as with food.. with half a body, you don't need to eat as much, and so you could literally eat yourself to death.
