Sharky may not have free access to the National Library of Medicine, so no linky.Link please? If this is "well-established" then a link supporting what you are saying should be easy for you to find and post here.
Basically, he is sort of right. If a person drinks socially, then those added calories will count, but if he consumes only alcohol (read: raging alcoholic), then he will lose weight. Alcohol contains 7 calories per gram. Since one drink contains about 14 grams of ethanol and alcohol contributes 7 calories per gram, it is easy to see why one serving of wine or Vodka contains about 98 calories (14g x 7cal/g = 98cal). Other drinks that mix alcoholic beverages like wine or distilled spirits with other beverages, like juice, will have even more calories.
One and ½ ounces of vodka for instance, contains 100 calories, but 1 cup cranberry juice and 1.5 ounces of vodka will contain about 230 calories. Moderate consumption of alcohol as part of a well balanced diet does not necessarily lead to weight gain. However, over consumption of alcohol, in addition to a weight maintenance diet can easily lead to weight gain.
Now, over consumption as in Sharky's example, can also lead to malnutrition and weight loss. This occurs when alcohol slowly replaces other foods in the diet. Malnutrition and other diseases stemming from the regular or sole consumption of large amounts of alcohol can easily be seen in long term alcoholics. The detrimental effects of alcohol coupled with the malabsorption of nutrients, vitamins, and minerals can lead to: WEIGHT LOSS due to the disease process of alcoholism and malabsorption syndrome.
