Some mixed drinks can have over 1000 calories. Beer usually isn't super high in alcohol, but each bottle of normal bear can be like drinking 1.5 cans of coca-cola.
Alcohol free beer is lower in calories, some brand is advertising 64 calories per bottle now.... but still drink 5 of those (or 3 normal beers) a day and you're taking in an extra 500 calories (a pound of fat a week) that you have to burn somewhere.
