How does drinking alcohol cause weight gain?

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.

For weight loss, avoid drinking excessive alcohol—not solely because of their own calories, but also because of the calories they inspire you to consume later. Alcohol lowers your inhibition so you end up feeling like you can eat anything and everything you see. Limiting yourself to one alcoholic drink a day has a protective effect on your arteries but could still cause you to put on pounds since it inhibits leptin, the hormone that promotes a feeling of fullness.
