Is it possible? There are some interesting studies:
- Chronic Ethanol Consumption Lessens the Gain of Body Weight jpet.aspetjournals.org/content/331/1/23.full
- Alcoholics, as compared with social drinkers, showed a lower body weight due essentially to a fat mass reduction: onlinelibrary.wiley.com/doi/10.1046/…
- Alcohol appears to increase metabolic rate significantly, thus causing more calories to be burned rather than stored in the body as fat. en.wikipedia.org/wiki/Alcohol_and_weight
So what?
