Alcohol (ethyl alchohl technically) is the least desired form of caloric energy for your body, although your body does actually require alcohol to live, but it gets all it needs internally. In fact alcohol and fiber are the only energies the body will throw out. It’s hard to digest of all.

Acetyle-CoA is super important to the “kreb cycle” which is the means by which the body extracts energy from food, but again the body makes alcohol naturally plus consumes it in all unprocessed fruits and vegetables, so there isn’t a need for additional intake to live (unless your an alcoholic, which is actually a physiological change to how your body digests all food and it basically leans heavily on Acetyle-CoA).
