The idea that drinking alcohol stimulates appetite and food intake is a common belief. While there is a limited amount of research in this area, what is available supports this belief. Small studies done mostly in healthy weight men have found that a moderate amount of alcohol (approximately two drinks) before or during a meal leads to higher ratings of hunger and food intake compared to times when a nonalcoholic beverage is consumed.
Theoretically, it would make sense that alcohol and excess weight are linked. The reality, however, is that the research connecting alcohol and obesity is contradictory. A few studies suggest that despite the extra calories, alcohol drinkers do not gain more than non-drinkers. More recent studies suggest that light to moderate drinking is not linked to weight gain, but drinking an excess of three drinks per day promotes weight gain. The reasons why are still unclear.

Alcohol contains calories just like food. If you do not take into account these extra calories, you can gain weight. Alcohol comes from grain and can be calorie dense. If you add high calorie mixers like soda or juice, the calorie content can soar. Another problem with drinking alcohol is that after a few drinks it is harder to stick to your weight loss diet. Alcohol lowers your resolve and you will be more likely to indulge. Sometimes after a night of drinking, you get hungry. Usually that means grabbing fast food. Fast food can be high in fat, sodium, and carbs which all contribute to weight gain.
