Having read the question [Is drinking alcohol a form of energy intake?](https://medicalsciences.stackexchange.com/questions/1313/is-drinking-alcohol-a-form-of-energy-intake), an answer cites the European Journal of Clinical Nutrition which claims Alcohol has a 'metabolic energy' (ie energy that gets digested into the human body). Sadly the link is dead and I can't find the information nor its sources.

All the papers or information I can find on metabolism of alcohol cite numerous pathways, but in my relatively amateurish reading, I can't see how any of these eventually lead ethanol into becoming glucose. Assuming it's true, how does it happen?
