The body is bad at breaking down alcohols, so much of it doesn't get broken down in the first run of the small intestine, instead it occurs more in the liver since the body sees it as a toxin and wants to destroy or get rid of it. The Liver can only do so much though, so if you have too much alcohol it'll start to just get pissed out as it passes through your body and bloodstream undigested.
Basically, if you just have one beer and drink it slowly you'll get nearly 100% of the calories. However if you drink fast and hard, like say you drink jack straight from the bottle until you can feel it, you'll probably only get the fraction of the total calories you drank.
People that drink beer all day get fat. People that slam back 10 shots every day all at once to get hammered immediately do not in the same way. Both are alcoholics.
Mori was drinking liquor throughout the day though, so she was a bit in between the two.
