Interesting. I wonder if it's because ethanol is derived from fructose initially, so the body basically converts it back first.

Undisciplined

OK, I've found my source. In this quite old [interview](https://fdrpodcasts.com/1565/the-politics-of-obesity-the-freedomain-radio-interview-with-dr-robert-h-lustig-freedomain-radio
) with philosopher Stefan Molyneux, Pr. Lustig argued that fructose acts very similarly to ethanol at the metabolic and cellular level, contributing to issues like fatty liver, triglyceride production, and even addictive properties...
It's a great and relatively short episode in which they both discuss Pr. Lustig's article, "The Fructose Epidemic" 

Also, it's important to note that we're talking about fructose, which is present in the food etc, and not glucose. Both are metabolised differently by the body.

US Sugar Consumption, 1822—2005

I don't know whether that's right or not, for sure, but people on ketogenic diets substitute sugar alcohols for sugar. That makes me think they're metabolized differently.

Are you thinking of protein, by any chance? Because, I do recall that excess protein ends up being metabolized like sugar.
