Actually this is not quite true. Your body uses carbohydrates converted to glucose for fuel. So only the things that you consume that convert to glucose will actually be burned. In the absence of glucose, your body turns to fat and or muscle mass for fuel. Those things that you consume that are not carbohydrate, protein, or fat, are perceived by the liver as toxic waste and excreted - including all alcohols that do not contain carbohydrates. Alcohols that do contain carbs (beer, wine, whisky) are not efficient sources of fuel - for example, "carb" calories from beer or wine will not provide your body the same amount or quality of fuel as equal amounts of whole grains, beans, or vegetables, and the "alcohol" calories from beer or wine are still perceived by your body as toxic and must be excreted.
There are 7 calories in 1 gram of alcohol, 4 per carb gram, 4 per protein gram, and 9 per fat gram. Alcohol is by far "more fattening" than carbs or protein, not quite as "fattening" as fat, but close. Not to mention the burden alcohol places on your liver and kidneys, which completely hinders your metabolic function, effecting how efficiently your body can metabolize the other foods you consume.
A healthy person can drink occassionally and not experience any long-term negative effects, but people with weight problems or any digestive, glandular, or auto-immune diseases would be much better off without any alcohol consumption at all.
